She is incredibly beautiful. Great job capturing her with the soft neutral colors... she really shines. I think I would have saturated her eyes a bit more, but I'd be agraid of retouching any part of her. Great photo. Wish I could vote.
Cool portrait which could have been optimized a lot more. More sharpness in the face, yellow tones out of the skin via layer mask, slight lightening of the retinas and a very slight lightening of the eye whites (also per layer mask). The full focus is on the blade of grass in the foreground, I would have blurred that a tad, it kind of pulls from your model.
I understand you what you were doing with DOF..but it was distracting to me. So I gave you a 5. Sorry...good photo..beautiful girl...just couldn't get past how much that grass bugged me.
