This is a pose that I have always loved and this quite beautiful model pulls it off very well. I shoot a lot outdoors and the lighting in this situation is very difficult and you have handled it masterfully. At the outset, the watermark pretty much destroys the image (I understand why you do it, but it really destroys the artistic value of the image). I like that she has some bruises that aren't photoshopped out. It gives the image credibility which makes this pose work--makes it come off as natural, real and comfortable for the model.
My chief criticism is there is too much negative space in the foreground. I understand why you shot it this way and the leaves from the plant in the foreground help, but I would prefer to have had about half as much foreground up to her very pretty feet and toes (I think this would still give the feeling and perspective of the scene and place much more of this exquisitely beautiful model in the frame). I would like to have seen this shot from a lower perspective relative to the model as well. It would make it less snap-shot like. Last I think it would be much better if she had been barefoot. I'm sure she needed the flip-flops to get up there, but they could have easily been tossed out of the frame. She has beautiful feet and toes that contrast nicely with the rock and the shoes detract from this and make her less naked and vulnerable in the woods.
Other than these minor criticisms I really like this image and appreciate how difficult it is to capture well, as you have done here.
