Good points mentioned by Lew, all of which I agree with it. In addition, I would suggest either going with a traditional black & white monochrome or colour, but this rather insipid sepia-esque tone is not what I think of as appropriate for children's images. I think #1 could stand to have a bit cropped off of the bottom and the RH side; I like the view of him walking away and the composition with the path is perfect. This is one (of VERY few) occasions when placing the subject in front of the leading line's vanishing point works well. I think the image would have been even stronger if you'd let him take one more step and be in the puddle.
This one does nothing for me; cropped arm and head, rammed tight against the RH edge... the garbage truck in the background adds a certain touch as well. Remember that the background is just as important as the foreground, and waiting 30 seconds for that truck to move would have made all the difference.
Just my $00.02 worth - your mileage may vary.
