my first poly model, the model isn't quite perfected yet (dodgy chin and lack of eyebrows/wrinkles) to name a few points, but i've been concentrating on getting the realism for the lighting/skin/bump+specularity, and this is as close as i can get it, any C&C for the realism much welcomed.

ps. could any 1 could give me a link for Mark Davies's 'ray diffuse' node, i've tried several places with no luck, and mental ray is no good when it comes to fur and paint effects, thanx
