thanks, yeah, I really need to practice: hair clumps and grass, they are my currently weakness :/
Looks good! In the future, I'd try to avoid the pillow-shading that has happened on the hair (Where you basically outline the lines in the darker color.) He has a fairly decent sense of where the light source is but really only on the face, the hair hasn't got much sense of light or shadow.
it looks good the shadow might be a little weird tho, good work!
