In my eyes the image is is a little bit off because of the door frame in the background. The whole image appears to be lopsided. And her pose isn't the most perfect one because one of her breasts seems to be way bigger then the other.
I know that it's the angle in which she is leaning towards the camera. That's why there is an distortion effect with the breasts. I just think that in my opinion there are several things a bit off with the picture which doesn't make it your best work.
