i agree that the crop is a little off on this one...it could go either way - tighter or looser - but as is seems a little constraining. I don't care if body parts are cut off, i just like to know that it's deliberate.
the black and white backdrop doesn't agree with her very well i don't think...it seems a little strong and pulls attention away from her. something a little more neutral might work better.
not trying to be overly critical, just sharing some thoughts.
I think the black and white hair takes away from the lovely golds and browns in the rest of the image. Her ear is cut off a bit too, which is distracing. Beautiful model. :)
