So you want to do a graphic novel. That’s great! And you think you have the writing and drawing chops to do it all by yourself. That’s great too!
But if you want it to be entirely painted, and your only idea of how to write is to throw a few characters into a situation and see what they do, you’ll probably never finish it.
Because comics take a lot of time. And comics don’t pay very well. And shit happens.
Figure out where your story is going, and how to get there in about 200 pages, and find an art process that won’t take too much longer than the pencil and inks of the B&W days. Or you will never finish your story.
(Me? I’m 10-20 pages away from finishing Decrypting Rita. It’ll be 200-210 pages, depending on if I decide to do the epilogue I’ve been debating the need for. But my mother dying kinda took the wind out of my sails for a bit. I’ll probably get back to it soon; I’ve been working on it fairly frequently for four and a half years now, and comics are kind of my day job thanks to Patreon.)
