Wonderful image of a great model. ^_^ It proves the right clothes are sexier than naked... you keep wondering what's underneath.
A few points I'll bring up. The background is out of focus and burned out. Out of focus is good, since it emphasize the model. Bit the extreme white of the background also draws the eye, and away from the subject. You usually recover the background through a technique called masking.
At the bottom right of the model, you can see part of a black skirt/pants. Personally, I'd change it to red, but that's a little thing.
Some would say you should Photoshop out the braces, I'm of the opinion to keep them. It's a personal choice.
Other than those few things, it's a pretty darn good photo.
