I'm pleased with that photo, @velimir. I'll tie that certain symmetry (if you can call it that) between the paper boat in the foreground and the castle in the background, which harmonizes horizontally with the top of the tree. There is also some coincidence of verticality by the tips (of the paper boat, the castle and the tower on the right). Also, a play of colors: from the pink of the boat with the child's t-shirt and the canvas chair, on one side, the beige color of the sand and a certain yellowish tone of the photo. Very nice photo, and the moment, of course!
