Looking superb.As your going for very realistic nipples what about a light bump map to go under it to increase the feeling of texture.This would be really effective for those who render in 3dMax.I,m not sure what plans you have for the pubic area but prehaps it would be best left "clean" & you could just use the Pubic hair prop,if you needed it.All in All, your well on the way to your goal of most photorealistic texture ever.The big question now is "what about the face".Hope this isn,t a set up & she,s got a moustache!
