Commission Slots Open + Upcoming Projects!

This is no April Fool's joke - my commissions now have FIVE SLOTS OPEN for the spring season! Check out my Ko-fi if that's something you'd be interested in. In addition, if you've been waiting to see more of my content, I have some special news - there are THREE upcoming publications with my work in them, here's some information about them below!

2026 MARTIAN ANNUAL

The first ever MARTIAN ANNUAL zine is right around the corner! This is a space and alien themed zine inspired by the format of real older magazines, run by @captainha-ha. I worked on a collaborative piece for this one, drawing with some friends of mine for a collaborative piece for a group OC project of ours, the Safehaven Brigade! 2026 Martian Annual is releasing April 26th, and you can read it FOR FREE here once it releases: https://officialmartianannual.carrd.co/ 

BEYOND SHAPES & BEATS

Now for my current passion project - Beyond Shapes & Beats is a JSaB fanzine that I am organizing over at @beyondshapesandbeatszine, celebrating the game and it's community. You'll see my own JSaB art inside, alongside so many brilliant artists, writers and creators from all over the community! Beyond Shapes & Beats is FREE to read and download, and will be releasing here on May 31st: https://beyondshapesandbeatszine.itch.io 

TRANSFORM & SUSTAIN

And last but certainly not least, Transform & Sustain is a Transformers-themed charity zine, raising funds for Forest and Bird, a New Zealand based environmental charity. I have a massive full page artpiece in the works for this one, can't wait for you all to see it. All proceeds of this zine will go directly to charity - keep an eye on the @transformandsustainzine Tumblr page so you know where to purchase it when it releases in July!

That's everything I have to announce for now! I have some more projects up my sleeve, but until those are ready to be announced, just stay tuned.

"Finding Families."

My own piece for the @beyondshapesandbeatszine - go check it out if you haven't yet, it's free! Featuring my own Blixer and sona, as well as the Blixers and sonas of several of my friends. This fandom led me to meet some of the most important people in the world to me, and what better way to honor that than include it in the zine.

Other designs by @glaciers-blorbo-purgatory, @jsabaddict, and @armadillocamel!

Back cover: REVEALED!

Finally, the reveal of our back cover in full! With 18 different artists, this collaborative cover (assembled by @bgsartcavern) shows how Just Shapes & Beats brought all different people together. Did you recognize anyone?

OUR WONDERFUL BACK COVER ARTISTS: @adventum-vaqui - @altromarnice - @alvilitytoart - @bgsartcavern - @beauh - @ckisle - @deltaqi - @dividedsingularity - @l00tkirby - @lukolucky - @lumhere - @pandoranoss - @poison-nekomimi - @real-ink-demon - @scindomundi - @slimyteeths - @soramarriaz - @spinnincircus

Beyond Shapes & Beats: A JSaB Anniversary Fanzine releases on May 31st - don't miss it!

[beyondshapesandbeatszine]

Something is coming...

18 characters. 18 artists. 18 AUs. All that together, and you get the back cover of Beyond Shapes & Beats: A JSaB Anniversary Fanzine.

For a zine meant to represent the vast and diverse community that JSaB has, a single artwork wouldn't fully encapsulate that uniqueness. Because of this, the front and back covers of Beyond Shapes & Beats are collaborative - with a different artist for every character. Do you recognize any of these silhouettes? Check back for the full reveal, coming soon!

Just 2 weeks left until Beyond Shapes & Beats releases - we can't wait!!

This week is Pentagon Week! We don't seem to have a complete picture of who these bad guys are, all we can say is that they're one of our SwapAU guys who kidnapped a Pentagon and played Russian roulette.

Funny :]

Thank you to these creators for giving us Pentagon >>>

it only takes an inch of water to drown.

Just a sketch piece made while experimenting with some dark colors. Has some personal meaning but is also just pretty, I think.

Might I offer my strange girlie?

[weirdozjunkary]

A quick reminder that I don’t condone the usage of generative AI with any of my ocs, stories, or AU’s. So if you see anyone use it, or if you have used it before, please either report the person, or take it down.

Thank you! Eat your vegetables! Byeeee!!!

[sapphtalks]

PASS THIS ALONG IF YOU don't WANT YOUR PRECIOUS BRAINCHILDREN GOBBLED BY GEN AI. THANK YOU.

[head---ache]

listen my art has already been fed to ai. theres already an ai model trained to copy my artstyle and it stresses me out. BUT IF I EVER SEE AI SLOP OF ANY OF MY CHILDREN? OOOOOOOOOOOOOOOOOOOHHHHHHHHHHHHHHH MY GOD I WOULD GO FERAL INSANE I WOULD CRAVE VIOLENCE DONT YOU FUCKING DARE. IVE ALREADY BEEN DISRESPECTED BY THAT FIRST PERSON. DONT FUCKING DO IT WITH MY CHILDREN

[bgsartcavern]

Reminder that this INCLUDES chatbots and characterAI. I would much rather you make some noncanon rp blog with my characters if you like them that much than ever try to plug it into an ai chatbot.

[bgsartcavern]
