Sharp and good focus. Seems like another simple snapshot of a child at play, perhaps a much tighter crop would raise the importance of the wagon as the subject.
I had one of those when I was little.... fun, low tech toy. I like the black and white here, and the kid's expression is cute, but I think this would have worked better as a tight crop, showing the face, the ensignia, and perhaps the wheels. The grass is just too boring, and yet distracting, a background for this.
cute kid! i think i would have liked this better if it was taken from a different angle. maybe if you had crouched down so that it was closer to "eye level" with the boy. i think that photos of children, when taken from standing height, looking down on the children, can tend to look "snapshotty". not always, though. just my opinion.
Good pose for the child, but there is nothing that jumps out at me. Maybe a different time of day when the shawdows are longer, like at sunset. You will be suprised how much this efects a photo
