I don't like this much at all. There is really no detail to honor this person with. She looks like a lovely girl, why not show that off? I can't comment on technical aspects like focus or lighting, cause there really isn't any due to so much post processing. The angle and framing/cropping needs some work though, in my opinion. You cut her nose right off. Sorry if I don't see this the way you do. Good luck in the challenge.
You have a nice composition here, but for my tastes, you went too far with the post processing. I can see the value in it, but it just doesn't work for me...
Very interesting "art type" portrait, that does manage to capture some expressiveness. The composition feels a little unbalanced to me, with just a little too much negative space for my taste. Overall though, I like the photo.
