EDW - Rendering tests

So earlier today I was playing with the render settings of ZBrush, seeing what it could do.  I think I'm missing something, but I'm going to look for some tutorials, see what can happen, but for now this is what I was getting.  A couple different runs with different settings and materials are below.

I also moved around the features to make him a little more asymmetrical, and now I'm going to do a little more than that.
