Here's the finished versions of those silhouettes from last week. I tried out a kind of graphic-y, cell-shaded look for this rendering, but I don't know how successful it was. I'll probably go for something more painterly/rendered for the next character line-up.
I'm working on another character bust for the project and planning to do some aircraft (dogfighting biplanes, fat bombers, crazy blimps etc.) thumbnails next weekend.
