A lovely model and such beautiful lighting. I would have found a lower branch to hang her hand so as to avoid pullin the eyes away from the eyes. Bumping up on great tonal value.
I like the idea here... especially the backlighting of the hair. Her face seems sharp enough. But her right shoulder is blurred... perhaps too shallow depth of field? It just seems odd because it seems like the trees behind her are more in focus than her shoulder. Another possibility is that her shoulder intruded on the minimum focusing distance of the lens (a real possibility if you used a telephoto/portrait lens). I love those eyes though... perhaps a tighter crop to accent the eyes would be just the fix for this image?
