Believe the composition needs to be improved here – horizon higher or lower in the frame – otherwise it is rather difficult to understand what is to be the subject in the image. Adding some object would also add a nice touch to the image. Good luck!
When I look at your photo it seems split into three distinct sections: sky, water, sand. Perhaps if the horizon line was lower or higher and not in the "dead" center, it would be more interesting to me, or maybe if there were some footprints or a bird or some other element to add interest.
