personally i really like this....it gets the mood across. okay, maybe it's no technical masterpiece as far as the grainyness goes, but i think it works well for this particular piece. the only gripe i have is with the ear lobe, a bit too angular and solid looking. maybe try a bit of a brown/baege tint to it..instead of pure black and white...but then again maybe not.
did you model this head yourself?
if i was your client...i would be happy.
