I find my eye keeps being drawn to the big rock on the right, I wonder if framing it differently, or omitting it would benefit the composition as a whole. I would be inclined graduate and darken the sky more as its a small bit on the flat side, but there’s plenty of potential there. My last point would be one of shutter, I wonder if a slightly longer exposure would make the action of the waves and the splashes more dramatic, were there limiting factors (lack of tripod or ND filter?) that forced the shorter exposure time?
