You are really improving with this one. Shadows are great, and i think you got a correct anatomy.
However, in the shadow parts, the darker zones should have, at the edge, a little of light, creating the round and 3D efect.
I don't like to share my things, but check this drawing of mine (http://art.ngfiles.com/images/225/thefoxharbinger_smail.png) to see how the shadows work, specially in the mask and the torso. Check that they get a bit bright on the edges, on the dark part. Is hard to explain.
Yeah, I think I know what you mean. Thanks for the review, I'll keep this in mind the next time that I do another light heavy picture!
