Here are some of the sample character designs. I have worked with Serapio to get to version 12 which which doesn't look so much like south park (variations in height- when your 12 or 13 your best friend can be a whole foot taller than you which I think is funny), but still has functionality in cutout animation. I also like having Doug being the runt of the pack- since he is the voice of reason - his friends look older but they act more immature getting them into trouble. No one listens to Doug because he is little is an ongoing conflict. I like set 12a the best.
From left to right Doug, Gus, Wiggy and Irv.
Here are some samples of the New character designs for Exit 9 (working title).
