I think, even though you are using a photo, you should smooth out the eye area a little, so that it appears to be concave. also, a bit of "noise" won't hurt it. here is one i am making...but, i am just painting mine....see how the shadows give depth to the eyes? i don't have a bump map on this...but the "noise" helps a little, i think. don't laugh, folks, this is just a wip...playing with deep paint and psp....not even antialiased...and optimized for jpg compression. my eye area needs more work, too.
