The backgrounds blend together quite well, but for some reason the girl seems to not quite fit with the other stuff. The light on her does not quite match the lighting in the background, which has a blue tint. Also, the waterfall on the right looks out of place on a second look, but not at first glance. Otherwise, the image is very beautiful and blends very well. I like how the water seems to be all one stock. I like how the girl almost looks sad, but for the waterfall/spout to look like it belongs, perhaps you should have had a more powerful pose.
