I don't really know that much about the correct use of ambient occlusion, but bagginsbill's shaders made me a believer. You'll probably find lots of good advice if you search for "ambient occlusion" in this forum, so I'm not going to repeat what little I've picked up.

I'll add a nostrils material if people think it's necessary. But there won't be an ear canal one, no matter how much you guys beg me. :tongue2:
