I recently enjoyed the Abenobashi series (Gainax). It was both hillarious fun and serious (I think some scenes were even a bit sad). I loved the character designs and the changes in their faces when they showed emotions (I love Gainax SDs - I already appreciated them in FLCL).
In episode three Sasshi was chasing the Goblin that stole Arumi's panties. It was my favorite episode because of the great puns of Kubrick's '2001'. But back to topic: The characters are taken from screenshots and were then edited. I had to redraw some parts of Sasshi and tried to imitate the sketchy outlines. The whole wallpaper looks kind of cartoon-like - I hope you like it.
