This has possibilities - some slight tweaking could make the difference - increase the dominance of the sun for example. One thing that's not very original, but who knows? - if you can do an after-the-fact distortion to curve the image *very* slightly, like a fish-eye, but *very* slightly. Another possibility is a gradual fade in brightness from top to bottom or whatever. This image is a good start on something, if not perfectly OK as is.
