I feel like the ratio between the sky and the rest is not right. When I'm looking at your photo, I almost never see the sky, my eyes stay "glued" to the salty surface. The sky is interesting with clouds and nice colors, but it doesn't exist for me.
I spent maybe 10-15 minutes watching your image and I agree with wolfnowl and raptorsys, I would either eliminate the sky or make it more present (hard to do without reshooting the scene).
But don't get me wrong, I like your photo a lot.
