Ok, compositionally this image does not work well to support the storyline. Without your explanation, it would not be obvious why the boy was holding his hands and had the expression he had. So, what if... you put the camera in portrait mode, put him in the upper right power point, (or upper left, to keep Trever happy) and showed the expanse of water in front of him that was causing his anxiety? By making the water a much larger part of the image, it would give us a clue that this was an important element. By putting the boy on the power point, there would be the natural shift of view of the viewer between the water and the boy, and back again.
