"Why did you make him green?" she says. 

I didn't want to leave him in paper-and-graphite, because he'd look like part of the rock he's sitting on. I thought the green would contrast nicely with the browns and yellows and blue in the background, more than if I tried to make decent flesh tones with colored pencils. I figured the green would also free me up from preconceptions about what skin color looks like and let me focus on shading based on shape and the position of the light.

Anyhow, here's what I drew tonight, and so far I like it pretty good :D

Thanks for looking at my picture!
