Beautiful sky, the colors are nice, but not over-the-top. I like the curving line created by wet part of the sand, and the way it picks up some of the sky's color on the right. You've captured some nice waves to add a sense of motion to the image, as well. You managed exposure well, I'm guessing this a blend of some sort but the result doesn't look unnatural or over-processed.
For me there's a little too much dry sand at the bottom of the image, I think you could crop some of that away to put the focus more on the water and sky. That one little wave/eddy that's creeping up onto the sand is also a little too centrally located, which I feel makes the composition more static than it would be if it were off-centered.
