I really like the direction Rich went. I'm a strong believer that hard-edged, blown-out areas like in this image pull the viewer's eye away from the subject. This is a different effect from the softer-edged, warm-toned, nearly blown out areas that have become very common among engagement, wedding and other romance-oriented photographers.
However, as Rich said, a bit more refinement on the folds of the cloth at the top of the head would be awfully nice. Also, IMHO, I would continue the vegetation throughout the entire background. I think that the white-ish areas are not very attractive. To me, they look like old bedsheets hung out to dry, LOL.
I would also crop the image to a portrait (ie, vertical rectangular) shape. The vegetation areas on the side don't have any real importance in conveying the personality of the person or the environment that the photo was taken in. I would certainly leave some vegetation remaining, just not as much as in the posted version.
Finally, at the risk of stating the obvious, if someone is intentionally trying to achiev3e the romantic blown background look, one should be sure that your lens and the mirror box of your DSLR are up to the task and not bouncing a lot of light around. There are lengthy discussions on photography discussion groups of exactly which lenses are best for this sort of shooting.
Just my $0.02,
