I think the lighting/positioning of the girl (perhaps to her left into the shade?) could be better to get rid of the blown out spots and the odd shadows making her nose look exceptionally large. Good idea for topic, though. (not voting)
I think if you shot this in the early evening then you wouldn't have gotten all of the blown out highlights on the left side of her shirt.. it's a big distraction. and, maybe try cropping it with out cutting off the book she's reading.
nic idea, the lighting doesn't quite work. If it were my photo I'd try editing using curves. The white shirt is challenging from an exposure point of view unless you make a feature of it.
Seems very much a snapshot I'm afraid. The subject seems pushed to far over at the edge of the frame and the harsh midday lighting is working against it. There are a few editing tricks that might be able to help with those bright highlights. Some careful use of curves, or some burning, perhaps. I would probably try some adjustments on a duplicate layer, since this is advanced editing, that would be allowable.
