This has the potential of being a great shot, the combination of harsh rock and soft sea, dry reds and calming blues. The concern for me is the high contrast of the rocky shore. Today's digital cameras have a tendency to adjust according to only one extreme in the composition, in this case it adjusted for the water, leaving the contrast of the rocky shore (pardon the pun) high and dry. When I'm faced with a scene like this I know immediately what will happen if I take only one shot. I don't know what sort of camera you used but, if it's a DSLR that allows you to make exposure adjustments, my recommendation is to shoot a range of shots, from dark to light, of the same scene (it's also why I use a tripod almost everywhere I go, allowing me to capture exactly the same view of a scene each tie I shoot). That way, somewhere in that range, you might get lucky and find you have the perfectly balanced image. If not, you can use photo editing software to combine the best rocks from one photo with the best water of another to arrive at a masterpiece. Normally I like my landscapes to be human-free, but I think you did the right thing with this one in leaving people in for scale... although I might have removed the adult in the swimsuit and left in the kid. Nevertheless, this is a good submission.

A great shot of the sea and this beautiful rock formation, Kostas. The color of the sea is just stunning. The people do give a sense of size of the rock formation.
