#2 is my fav--would be better if crop was not at her knees, but that doesn't bother me very much. You might crop out some of the negative space above her head & keep the knee crop--might give some balance there. Unlike the others, I really like #3. I would lighten the whole image just a tad, though. I like the background--she really "pops" against it and the jewelry is killer. #1 is good--her arm & hand don't bug me at all--but I do agree her facial features are too soft, especially compared to the sharpness of her eyes.
But these are merely my opinions & what I would change to make them appeal more to me. I wouldn't trash any of them as they are.
