In addition to what has been written (cropped feet), in my opinion the greed hedge in the background draws a lot of attention away from the child because it is so heavily saturated.

Since the background is green, a colour far away from any skintones, one could try and desaturate the green of the whole picture a little.

How far you go with this is a matter of taste. I desaturated green and also yellow (which often helps with leaves more than pure green, also this reduces the saturation of the curb). This of course also affects the rest of the picture; you can see a big difference with the green and yellow sides of the ball. But in my opinion this does not really hurt the picture.

Another thing whith the white balance in pictures whith a lot of green (leaves, gras etc.) in them: my own camera tends to bring up the tint to high in automatic white balance, as if to compensate for too much green. Maybe your camera does that, too. Try to manually reduce tint in these cases.

Now, these measures might seem counterproductive. In my opinion it is always important to get a correct white balance first, and then change colours/saturation to your liking, especially whith faces in the picture.
