Dani, it is the composition of the 2nd shot that really makes it unique. The placement of the people, especially with the child to the far left and the body language of the child and the adult, plus you add in the beach ball caught in mid flight whch seems to be blocking the sun- these are the elements that drive this shot.
If I were you, I would play around with it even more and try to darken the foreground more while lighting up the sky a bit. Maybe even convert it to B&W?
Nice shot
