Nice modeling, my only crits are about the edges in the ear structure that are a bit to sharp I think, as for the outer borders of the nostrils, and also the mouth borders looks a bit weird.
The likeness works well, maybe her jaw should be thinner, anyway congratulation.
Your skin shader seems to work really well,the SSS effect is subtle enough and the specularity works fine. Try it first with a classic 3 lights setup but contrasted to better feel the SSS effect, 2 coming from the sides with one stronger than the other plus 1 strong back light for the ears And when you 'll put the diffuse textures try to keep it desatured as much a possible, this is the key for a good skin shader.
By the way, Do you know the Zap Anderson’s tutorial ( get it here: http://www.lamrug.org/resources/skintips.html) it’s very informative about The MR fast SSS Shader.
I’d be curious about your displacement rendering process in Max:
-Did you use the MR displacement node of the Skin shader or the Displace modifier?
-700 000 Polys is polycount of the model imported straight out from Zbrush or is it after smoothing?
-what was your render time with such anamount of poly + SSS at what resolution?
Thank you
