The style holds up well across characters. So you're really got something going there.
A strategy to consider is that used in traditional comic books, of doing an entire story in pencil with simple thumbnails, each with dialog and notes about who is who, background, etc. and revising that until you're satisfied, then doing the finished frames but reusing character figures were possible (some resized with your software) and making new figures as you need them, building up a collection for further reuse. And skipping around in making completed frames helps you see what you need to finish one comic, since frame No. 3 might be a modified version of frame No. 47. And, of course, doing the frames that would take the figures you've already got first would give you a running start and let you see the whole thing partially completed.
