Last time we learned about conceptualizing our characters, settings, art style, etc. Now we actually have to put our characters in a situation, drive them from point A to point B through a story.
There are many different ways to do this. I'm assuming you have, if not an outlined story, a situation you want your character to experience. If you don't have a story, make your character order pizza but something happens and they have to rescue the pizza (and the delivery guy, I guess.) The first method I'll discuss is my least favorite- the Script Method.
You write a script for your story, listing pages and panels as you go along. I hate this. It feels too limiting, and panels are actually one of the most limiting and intimidating things to a beginner comic artist. Yet most tutorials encourage you to draw your panels first and then squish or stretch your drawings to fit, and that's what the Script Method is based off of. I draw my panels while I do my drawings, or even after I do them.
If pacing your comics is one of the most difficult things for you (what size do I make my panels? Is there too much dialogue on this page?) then I suggest the Storytelling Method.
You do not have to make a full short story or book. Usually I just say something like, "boy is making cake. girl walks up behind him and hugs him, kissing his floury cheek. she walks away, licking her finger. she has stolen some cake batter and he didn't notice." In my head I can see a more detailed story there, but you can tell a story without a bunch of flowery prose.
You may be wondering how this helps with pacing your comics. Well, I have actions associated with dialogue, meaning I know which drawings will have which dialogue, automatically creating a nice balance. Additionally, I know what to prioritize. I know that the panel introducing the manor will be large, because I used the words "large and imposing" to describe it. I know that when I set the ballroom scene in this story, I also need to set the scene in an establishing shot. And I know that I'm going to have Bernice's appearance on the food table be surprising, taking place after she tugs his shirt or something. (This will probably make more sense once I actually make the comic)
The final method is a very flexible one for those who aren't into words and just want to draw- the Children's Book Method.
This particular example is mind-mapping, but you can also do a more organized version by storyboarding (placing each drawing in a square and giving a short description for context). I call these collectively the Children's Book Method because the basic idea is that you don't repeat your drawings like you would in a comic. Instead, you draw those things that feel the most interesting and most dynamic, the things that are most important. (like keyframes in an animation) Children's books illustrate one scene at a time, providing context for many different moments in one picture (and some text). They are less sequential than a comic because they only have one picture per page.
I usually have a mix of the storytelling method and the storyboarding end of children's book method. And usually I tell myself a story only in my head, without writing it out, because that's all I need. And I'll admit, sometimes the stories play out in my head like a movie, which is probably why the script method works for people. Sometimes you don't know which is the most effective way to tell yourself a story until you try to draw the comic and see what is giving you the most trouble.
If you have any questions, feel free to ask me! I know I'm kind of rambly and don't make much sense, so if you need clarification or other tips, I'll do my best to help.
Next is Panels and Pacing: Drawing the Comic (which will probably happen in multiple posts, but this art block will make it nigh impossible for a while, why doesn't it just go away?)
