Reworking the face

I recently saw some pretty awesome human renders and reevaluated where my head model/shader/lighting was at and it was pretty rubbish. I spent some nights this week redoing the shader, refining the sculpt, making new eyes and changing pretty much all the maps. It still needs a fair bit of work, I have to test ways to get some softness into the eyes and there is too much bump and spec on the neck, but at least it's better than it was.
I also decided to only do minimal post stuff on my wips (just a zblur for DOF and a slight defocus to remove cg sharpness) as it hides problems that should be fixed.
