You mean aside from the adorable child?
The colors are a it strong, but it enhances the young feel of the picture.
When I first saw it, it seems like all the elements of the picture funnel me towards...the weed!
The border between the grass and the concrete, the border in the concrete, the cascade made from the child, to the ball, down to the weed.
We can't always compose these shots perfectly, that's for sure. I'm just nit picking for the sake of critique here.
