I like the gradient in the sky, and the concept, but there are several things that detract for me: the sunglasses, the very large part of the image that's pure black, and the tiny size of the kite.
honestly the first thing that caught my eye was the out-of-focus arm. it might work better if it were in focus or more out of focus. it looks like neither. i like the perspective of the shot but i think the kite would look better a little closer.
