I like this one better than the others, she looks like Asami from The Legend of Korra. I will say that the other facial strutures are no where near as good as this one. But over all the lighting is superb, good enough to be a skin, you should send this one to summoner showcase.
She looks great, you did a great job, and your redesigns are A-M-A-Z-I-N-G! BUT I have to note something: you must contour the noses a little bit... I mean they look REALLY flat, like Voldemort from Harry Potter... Sorry for sounding so mean but I wouldn't five you feedback if you weren't such a talented artist!
