'allo
i like the top one, the clouds by the house are wicked - i'd crop it in closer though if i were you and get rid of the people. that way you get a better feeling of the beach and the sky as an entity with the house bridging the gap
the second one is a niceish view but i'd lose it to be honist - too much going on and not enough central focus of subject - again nice colours tho
i like the concept of the 3rd one but the action is wasted being so far away - everyone knows the sea is big so you needn't get much of it in, if you pull the shot in tighter toward the girls and take it from slightly lower down going up at a slight angle then i think it would look more dramatic and charismatic - it would also make the waves look bigger
hope i helped
