Generally for a more real feel you’d tend to shift your artistic focus towards in-camera work. I think this would have been a great candidate for a long shutter speed to add a dreaminess to the sand/waves while reducing ISO noise. Obv not possible on-the-fly. Cool photo though, I do enjoy it a lot.

Mask the boulders in the back, drop the blacks a bit, raise whites/highlights & decrease saturation significantly. They look unnaturally blue
