I suppose my lighting is a bit strong, but it's just a white plane, and AO at 0.25.
This one hell of a node set-up but I'm wondering if it's really necessary ?
Coordinates and mapping shouldn't really be needed if you made a UV map for the skin and a normal map is probably not required either, as it's a smooth skin and you are not trying to create, acne, pock marks, wrinkles, etc.
The gloss image texture, I assume, relates to the lips? Although when I have done glossy lips before I highlighted the vertices, duplicated them , made them a separate entity, diffuse red and applied a solidify modifier - it gave me more control as I could mess around with the transparency also.
Hair is a pain, did you make particle eyebrows? . .I tried that once, never worked for me.
I must also point out that I can't use my Graphics card for rendering, so I do try and keep things simple.
