I think I can see pores in her nose! :D
The teeth/smile still looks a bit unnatural...maybe because they're too perfectly straight/aligned or something. the lips themselves look great...just the teeth when she smiles.
But yeah, I agree...best digitized human face I've seen, probably. I'd like to see the hands upclose/in motion. They always seem to be one of the hardest things to do - or at least an area where they cut the most corners in favor of other areas.
