As nice as the sand and sky are here the wide angle makes it hard to see the surf. I think it would be better if you had sacrificed the negative space of the sand and sky and zoomed or cropped in more o the surf.
Pretty blues and I like the motion of the water going out in the foreground. Surf looks a bit rough to be peaceful, though watching it could be, I guess.
The receding tide reveals lovely textures and tones. For me, the photo would be improved by a simple straightening of the horizon, which seems to be out by about 2 or 3 degrees.
