Animal Man a.k.a. Buddy Baker. This guy is an old school DC Comics hero who could take on any abilities of an animal. He underwent a resurgence of popularity in the 80's when notable comics writer Grant Morrison took Animal Man's comic and started writing crazy adventures where Wile E. Coyote is a Jesus archetype and Animal Man drops acid and starts talking to the comic book reader. Did I mention that Grant Morrison used to do serious drugs?
Anyways, Animal Man was drawn with a G2 gel pen and a fat tipped Sharpie marker. The animals in the background were drawn with a smaller pen tip- a .01 cm tip pen- to get the fine sketchy details. It was then shaded over with a dried up Sharpie to give it some depth.
The animal that I like the least in this picture is the snake at the top left corner. It looks...well...not very snake like. I don't know what it is. The picture looked better in my head.
