Light Penatrates the skin

So, this update is subtle but is going to help me with other stuff. I was working with some different lighting schemes for different angles and more dramatic type lighting, but the way the skin was absorbing the light I didn't really like it.



If you look under the nose of Ed here you'll see that the shadow is a lot more darker now, which is actually correct since I don't have any lights hitting that spot so it should be pretty dark. His eye area and surface detail are also now getting blown out as much. I also added some other maps to the shader to control the light and bring up the detail some. This is my first skin shader that is not a blinn with 3 maps for a video game so I'm learning as I go :).
