I like this... a lot! But I think it might make it a bit more dramatic with some cropping to move the rock more to the upper right. Maybe up a bit, and over to the right to about "2:00." You'd definitely want to keep the "tails" though. Either way, very nice.

where's the beach?

It is a beach, has sun, sand, sea waves and swimming people every summer there.

Love the smoothness of the sand, and the trails the water left....and the odd way the rock looks like it has a face. Gives the illusion that the rock is alive. Excellent shot.
