This photo has some wonderful elements working to its advantage, particularly the long exposure and the "ghosting" of the water over the rocks in the mid ground.
I do see, however, two competing photographs that turn this into a bit if a back-and-forth tennis match (or I've watched too much of the US Open). There is detail on the left and the right with a swath of "empty" water and sand I between disrupting the natural flow of the photograph.
The foreground rocks on the left could play a more significant role in a similar composition shot from slightly to the left.their bright greens demand a closer look. The beautiful rocks in the upper right could also be a photo in itself.
