Thats awesome nice work! Crits: - The nostrils kind of bug me, too much build up around the rim and they don't really look like they go anywhere, they're like big moon craters. The hair on the back could be blended a wee bit better, probably just darkening the diffuse underneath or painting some subtle hair on the diffuse…
Ah yes, good 'ol secular lighted, no fuzzy religious parameters. Joking aside, this looks really good. Maybe darken the diffuse so your spec comes out a bit more popping. edit: oh crap, jokes already been made, damnit.
