Working digitally actually does make problems like that a bit easier. It’s kind of like filmmaking, where the art is your footage, but you can reorder and move things around a lot in the editing! I may need to do a bit more drawing then or change a panel or two, but going back to the film analogy, those are just “reshoots!” 🤗
Honestly, it usually works out pretty well. I’ve blocked out how many pages I think each scene will take, and just by reading & studying a lot of comics and thinking about how I want to pace a sequence, I’m usually pretty accurate. I’m also interspersing some mock advertisements, so those can be cut or added as the story pages might demand.

Thanks for the support! I shall continue!
