Texturing the bust

I started texturing the face in ZBrush 3. I've been playing a little with material settings to get a semi-realistic skin shader. I don't think i can get the results that mental ray would, but its not too bad. I need to learn a lot more about the material section and metCap features that ZBrush has to offer. Lighting needs a lot of work, but i won't start playing with that until its time for my final render. I found a little trick too with rendering which gets rid of the aliasing around my object, it has come in pretty handy. So, It's getting there and I'm learning tons right now. I need to learn how to assign different materials to different sub tools. so, I'm off to figure that out now. Let me know what you guys think...
