I've basically got two books going now. One is in the ending phase, where it's all drawn and figured out, and that is really left to do with it is editing and clean up. The boring stuff.
The other book is in it's nascent phase, where it's still taking shape. I've been doing these little drawings as stylistic tests. I'm basically just figuring out how this next book will look. At the moment my plan is for 48 pages of splash pages with a lot of crosshatching.
