Perhaps if you chose a different colour background you could better blend the rest of the body with the picture. I have to say it's either all black lines or none at all.
I do like it, but I don't think you needed to be so gung-ho about getting rid of ALL the black lines. For instance, without those black lines, certain parts of her seem kind of odd to me. (Her cleavage, her butt and thigh, her hair and her chin, to be specific.) Don't get me wrong, I still think that you did a good job, but I think that there's still room for improvement.
