Incredible result. Eyes are not on par with the rest, however. Could you add SSS material on the eye-white, I think that would bump up the realism a notch.
Yup, it definitely looks a bit better now. The eyes could also have reflection maps, but they should be properly shadowed or it looks weird. Eyes are hard, I've not seen anyone do them perfectly yet, even in offline renders.
So that's what was making me try to figure out why there was something not quite right about the face! It seems we tend to notice little details like this more unconsciously; it's probably a huge contributor to the uncanny valley effect.
