Ok, here we go.  IDL with a 3 point light setup (main, soft, and rim).  If all goes well, gonna use this image and fade/blur the background (depth of field), this will be a simple up close detail of face & texture with eye icons on the right side.

Again, edited the texture to look true blonde, different hair by same vendor, Ali (I really love this vendor's hairs).  Edited the material to be more bumpy and specular (specular maps aren't necessary as the bump does the trick).

What do you guys think?

Much better, but dump the background!  All it is doing is distracting from the subject - way too busy and that grass sucks.  Use a simple background in post by rendering on a white background in Poser and save the file as a PSD, then drop it on a simple background. This hair is better, but still flat and too deeply shadowed.  Another distraction from the subject at hand. 

Quit doing artistic renders and do PROMO renders.
