Interesting capture but it could be so much more. The dog is looking away from the scnene and the boy is looking at the camera. If they were looking at each other or if they were both looking in the same direction it would definitely establish a connection.
This has great potential. The focus is more on the dog than the boy. I might work on it so that they are equally focused. I might play with levels or curves to enrich the tonal quality OR do it in black and white with high contrast.
