Hi! I was going to join but the idea I had for it was going to be a redraw of a past piece I did a few years ago along with a brand new second piece to go with it, is that okay or does it need to be an entirely original idea?
Hello!
While a (not 1-for-1) redraw would be allowed as a secondary piece in the event, your main artwork piece that would need to be 50% completed for claims would have to be the brand new second piece you mentioned in your ask, as we are not able to easily quantify how much of a redraw would need to be changed to qualify as a "new piece", and the event requires a new unpublished piece to be used for claims. If your author and you can come to a consensus on the redraw, and how that fits with your main artwork, then it would be allowed to be included in your collaboration.
If you need more clarifications don't hesitate to react via a reblog or another ask !

hii! if i was thinking about doing an animation/animatic for my part of my submission as an artist for the reverse bang, what would the requirements for that be? would that be allowed?
im not 100% sure i could commit to that, but i figure i should know what i would have to do if i did
Hi!
An animation/animatic would certainly be allowed! As we've never had an artist utilize this medium before in our prior events, we'd want to discuss with you specifics to make sure that your time contribution would be equivalent to a traditional drawing artist's for the minimum requirements. If you want to reach out to us via DM we'd love to discuss it with you and then we can reblog this post with our agreed upon minimum requirements for any other animation/animatic artists who might be interested!
After discussing, we have decided that the minimum length of an animation will be 10 seconds. The 50% requirement for claims must include the key framing scenes of the animation in order to give authors a good idea of the animation's story, but the 50% requirement does not apply to each individual frame (ex: if a 10 second animation requires 60 frames, you do not have to have a rough sketch of each of the 60 frames. You can have the first 15 frames nearly complete, and then 15 other frames that describe key moments/movements later in the animation nearly complete for claims).

WIP Big Bang International Fanworks Day Mini Bang 2026 - Schedule & FAQÂ Â
Schedule
All times are by 11:59pm PST. Convert time zones.
Writing Begins-Â January 9th
Earliest Posting Of Fic To Platform Of Your Choice-Â February 1st
Regular Posting Of Fic To Platform Of Your Choice-Â February 7th
Bragging Rights Posting Starts-Â February 15th
Bragging Rights Posting Ends-Â March 1st
What is the WIP Big Bang International Fanworks Day Mini Bang?
Good question! This is a Mini Bang with one goal in mind: to clean out your fanfic drafts folder for the fics that were too short to be completed during the main Big Bang (ie, finished works are 7.5K words and under).
Do I need a Livejournal/Dreamwidth/AO3/etc. account to participate?
No! You don’t have to have an account on anything to participate, though you will need to have somewhere to post your finished work. Having one or more accounts will help for you to follow what is going on with the bang (we cross-post to Dreamwidth and Tumblr and heavily use our Discord server at the moment), but they are not required to participate. You can always leave comments anonymously or with an opensource ID.
How many fics can I write?
We absolutely don’t mind multiple fics! There are no sign-ups for this, as it’s an informal Mini Bang, so as long as it stays under he max word count, you can finish as many fics as you want between January 1st and February 15th.
Will I get emails about the bang?
We do not send out any emails for the Mini Bang, as we currently do not keep an updated email list of participants, so we only send individual emails as needed rather than mass emails.
However, email is the fastest way to communicate with the mods. If you have any questions or are having trouble communicating with your artist/author, please do email us! We will do our best to respond quickly.
What do you mean by maximum word count?
You don’t have to have a set minimum of your fic to start, so an outlined fic is fine, but it must be under 7,500 words when it’s finished.
Are multi-chapter fics allowed?
Yes, multi-chapter fics are allowed, as long as they stay under the maximum word count.
What about fics that are already posted on AO3 in part? Do those qualify for the bang?
It's okay if you have posted some of your fic already (you never know when the muse deserts you, after all), we just require you to refrain from posting more until posting begins here. All we ask is that you not post any public updates to the fic until February 7th (a week before posting your bragging rights to Dreamwidth and/or Tumblr starts). We don’t want you to lose kudos and comments so don’t worry about pulling the fic down, just hold off on updates for now.
I see that the fic maximum is 7500 words and that published WIPs are acceptable - but what if the WIP I’m considering is already more than 7500 words?
If your WIP is already over 7,500 words it is ineligible for the Mini Bang. However, you can submit it for the regular WIPBB in April.
What happens if an author finishes the fic they signed up with but it’s more than 7,500 words? Do they have to drop out at that point?
By all means, we want your stories to feel as natural as possible, and if it’s over 7,500 words when you finish it, that’s great because you finished the fic! But you can’t submit it for the International Fanworks Day WIPBB Mini Bang because it’s over the maximum word count. But be proud of yourself for finishing the fic!
Is there anything not allowed?
As long as you wrote it and you want to finish it, you're welcome to participate. Original fiction is fine. RPS/RPF is fine. Incest pairings are fine. Things like that I know have been hinted at in questions asked and as long as you tag for them, we’ll allow it. Also, canon settings with mostly OCs are allowed. We just ask that it be tagged properly with any content warnings you would deem fit and be given the appropriate rating for the level of sex/violence there is in the fic.
What's the etiquette around OC-centric stories? Ones that are set in a well-known fandom and use several characters, but still lean a lot on original characters? Are they discouraged, or fine?
As there is no art claims for this Mini Bang, having mostly OC-centric stories is more than fine.
What is, and do I need, a beta?
A beta is basically a person who goes over your work to make sure that there are no spelling/grammatical errors, and they can even be of assistance in helping you with story lines, etc. It is highly recommended that a beta looks over your work before posting. If you are having trouble finding a beta, try the Discord community.
Where can I post my fic/art?
Stories can be posted to your own personal journal, Tumblr, ff-net, AO3, or wherever you like. For those of you with AO3 accounts, we will set up a collection that will go live on the first day of the posting. If you don’t currently have an AO3 account but would like one, you can contact the mods for an invitation code to see if they have any available. You can also add yourself to the AO3 Invites Request queue.
What does posting look like? Do we have to post the whole thing on the day, or can we stretch it out between when posting starts and our date? I’ve had a few longfics get killed by big bangs forcing posting to happen on a given day and would prefer to avoid that if possible.
For most fics, posting to AO3/FF.net/other places will be allowed to start on February 7th and you can stretch it out as many posts as you want as long as the complete fic is up by the posting dates (February 15th to March 1st). However, if you need to post earlier you can start posting February 1st. We want to work with writers to give them ample time to post the story up to their posting date.
Now, as for posting to the communities, you can post at any time between February 15th and March 1st, without picking a posting date. You’ll post bragging rights similar to those used during the full length WIPBB to Tumblr and/or Dreamwidth with a link to your fic and your bragging, if you choose to include that portion.
How come there aren’t 'art claims'?
The quick turnaround in time and the length of time set to write doesn’t leave a lot of time for artists to make art, so the only art allowed to be posted during this event is unfinished art from the 2025 round that has been finished.
Can I get an extension?
Community extensions may be given in the event that the majority of the authors/artists need one. They may also be given individually under certain circumstances, but this must be discussed with the mods and will only be a short extension for posting.
Can I swap out a fic if my muse abandons it again?
Since you’re not signing up with specific works, you are more than free to swap fics out with other ones.
Can I drop out?
Absolutely! This is a low-pressure event so since you aren’t signing up to finish any particular fic, you can drop out of the event without telling the mods as well.
Are we allowed to participate without joining the Discord?
Absolutely! The Discord server is optional, as just another way to interact with your fellow writers and get updates on important dates. It’s not mandatory you join, however.
I was just wondering if there’s any way to enter the bang anonymously? Like would it be okay to put our work in an anonymous collection on ao3 or something?
Unfortunately, I can’t think of a way for that to work. The collection that we use is moderated but it’s not anonymous, and there are the bragging posts that you post to Tumblr and/or Dreamwidth, which you would have your username on whichever platform you use. If you don’t want to use a Tumblr or Dreamwidth account for posting your bragging rights, however, you can always send them to the mod account, and we can post them on your behalf.
I was just wondering whether I'm sworn to secrecy on which fics I'll be finishing up, or if I can shout it out to the world?
No one is sworn to secrecy once they’ve picked a fic to write (aside from posting new parts to fic that’s already up somewhere…we ask that you refrain from doing that until at least February 1st)! If you want to share snippets of your fic as you make progress, that’s fine, just don’t share the whole thing until posting time starts.
I have a question/concern that’s not mentioned here.
If you need help, you can always contact a mod, and we will do our best to make sure that you get your story/art finished. The best and fastest method of contact is through our email, [email protected].
Just a friendly reminder that you can start posting fic updates to the platform of your choice for the mini bang in three days if you want to space out multi chapter fics! Posting to the Tumblr and Dreamwidth accounts will start on International Fanworks Day, which is February 15th.
AO3 collection will be created and posted January 31st
