Nice idea and strong compositional choices.The image seems a bit unclear to me. Perhaps adding some contrast or bringing up your neutrals and darks would help. I like how we are not able to see the boy's face. It gives it an 'everyman' feel.
This shot is crooked and a little busy. Boy and foreground ducks would make a cleaner presentation. Crooked part is easy to fix in photoshop if you have a good vertical or horizontal reference in the shot (the reeds maybe).

Good rule of thirds and subject. A polarizer to cut back some of the blown areas on the water would have worked well. The focus is a bit soft, need sharper focus on the subject to make it stand out more.
Not a bad shot, just wish it had more detail. If you would use a tripod or hold the camera perfectly still you will get more detail. good luck and keep shooting.
