This is one of those artistic shots that rarely does well on DPC but is worth exploring again looooong after the challenge. My only wish is for her face to be sharper, or at least her eyes.
Just seems a little out of focus. You may have intentionally gone for a dreamy fairy tale bloom/blur effect during post processing but I feel the eyes just are not as sharp as they could be. Perhaps just a bit of sharpening on the eyes or even just a small USM after the resize to 640 would have made all the difference.
