The balance of sky and sea is magnificent. Even the colors are stunning. How ever placing the humans on the left does not add value to the shot and I guess this shot will be better without them. The main reason I think like that becasue the postures and the cloth colors does not add up to the over all shot.
Nice harmony of colours between the deeper blue of the sky and the lovely pale aqua of the ocean! I agree that the people should be cropped out, although this might be hard because then you would loose some of the beach which (without the people) wrapps nicely around the big aqua pool in the foreground. The people are a little too distracting thou, they tend to stop your eye halfway instead of allowing it to travel out along the half submerged rocks.
