I had a drawing lying around and in a moment of unrest coloured it up in Photoshop. Usually I light my drawings really simply...you really can't get too complicated with flat colour :) And this is still simple lighting but I tried throwing the light from a lower angle. The background is more than a little lame but I hope you'll forgive me.
The drawing is referenced from a pose found in the Physique Pictorial collection. I love those books.
