Ben Towle has been working up his characters for his next graphic novel, In the Weeds (which sounds like it will be set behind the scenes at a restaurant), and he shows off his thought process at his blog. The book presents some challenges:
About half of the book takes place in a restaurant kitchen and this presents a prickly problem in that everyone will be dressed the same. It’d be really easy here to fall into an “Alien 3″ situation here where you’ve got a bunch of (mostly) white guys running around in the same outfit and you can’t tell who’s doing what or saying what unless you’re seeing a close-up of their faces.
It's interesting to see how much the characters change as he refines them.
