A few things I wonder about: The specular color is black, the specular value is 1.0000 and the highlight size is .3000 I doubt you want "black" highlights - try either setting the specular value to 0.0000 or change the color of the specular color and see if that doesn't address some of the darker areas of wierdness. For the lighter areas of wierdness I'd experiment with less bright colors for the sheen on the skin node. I'm just guessing, but these may be worth looking into. Unzipped
