I'm afraid there's not much to C&C here. This really seems like nothing more than a family snapshot of a day at the beach. While it may hold a particular memory for you, for us, it does nothing.
Horizon is crooked
The boy is bent over showing nothing besides his butt
The girl on the other end is pulling up her suit and her elbow is covering the head of the little girl
The colors in the other little girls swim suit does not match.
Sorry, but its just not a very appealing photograph.
