You are a very good photo manipulator. The only think that bothers me with this one is that there should be some plants and/or grass hanging off the edge of the cliff (near the girl's feet and the roots).
But just one little tiny friendly remark, is that you could maybe add just a tiny bit of shadow, under the lady's feet at where she's standing, cuz her feet don't really seam to touch the ground. It's what we call slagschaduw in dutch (i think cast shadow in english) and its the shadow that's always there, where objects touch each other, and in folds. For example, the shadows in between your fingertips when you press them together. So i think a little dark line under her foot will do the trick.
