Pretty good!
The kid is a little small in the frame, in the first one, and the whole thing looks a little tilted. Obviously he's leaning, but it feels like the camera must be tilted too (could be an optical illusion, though)
Second one's just plain cute.
Third one ditto. Again the kid is a little small in the frame, but I feel like it works better. The highlights are not well treated here, so I cannot tell what he has in his hands, which is bothersome.
