Here's an "after" close up, the differences are subtle. 1)the wierd highlight due to the back light is gone (I turned off the backlight) 2)the shadow from light 2 is nearly gone (I turned off the shadow, and set the map and shadow to 0 for that light) though some shadow remains from AO which I can live with 3)adding a slight displacement to the eyewhite via an inverted texture map has added just a bit of depth to the highlight 4)removing all specular values and effects from the iris and pupil has given the eye more depth, but it has also created a greater contrast between the areas covered by the cornea and the areas that are not.
