i Would definitely change the composition and not use the tree in all the shots, as background. I like the third shot of the young girl, where i would clean up the skin to remove her zits, as i am sure she wud not be happy with that. Regarding composition most of the shots appear to be a similar style shots where the subject is looking straight at the camera, since there are kids i would prefer it to look really playful and some candid's would look like they are having fun.
retouches are better but pls get those zits cloned 
. The second one I admit was a quick retouch and a bit lazy on the cloning part as I was more just trying to take the ideas given to me with the editing of the white bal, shadows, exposure, and tree lighting rather then a full on edit. Granted cloning doesn't take that long though so I really don't have much of an excuse.
