Quite stunning
She looks like a girl in my class, only this one's taller and not as French-looking. Anyway, as you said, this really is photo-realistic. My favorite part is the hand; it is just totally realistic. I do see the mistakes you mentioned after glancing over it: the leg positions are a tad odd, the right (her left) forearm is gorilla-sized, the neck is too wide, the feet are too rough, and some lesser ones would be that the ripples on the top half of her dress aren't perfect and that the background is too blurry. Also, I think the head is a little too big in contrast to the rest of the body.
