Beautiful girl, nice soft focus, captures her essence very well. If I'm offering some constructive comments, I'd have to say that given that this was an expert editing challenge, the background might have been changed to something without frames behind your model and perhaps, a bit of a vignette appearance around her to emphasize her beauty. :) This way, against the others that are expert edited...it kind of has more of a "snapshot" type of look and feel to it. Still a beautiful model. :)
This is a very natural portrait, that could score higher if that was the challenge theme. But this challenge was about "Expert Editing", and I cant say I see it here. (maybe some cloning on face?, but thats not "Expert", is it?)
As a portrait, I would have tried not to get those picture frames in the actual photo framing.
