She's levitatin..

Pretty cool, but I see what the problem is with the dress... It should be more voluminous on the bottom, with more of a trend in the billows of the fabric to the right of the picture, since the wind is blowing in that direction. You could also work on the angle at which the person in the picture is viewed, to make it more dynamic and interesting... Also, there should be more detail in the sky and to the stalks of the high grass below...

You know, this kind of reminds me of those scenes from gladiator where Maximus is all floain' around and shit :D
