Good composition with child not dead center in picture, except for a little too much foreground dirt at bottom and left... I'd crop a bit more of that out. Nice reflection which makes the photo. The square pink object behind subject looks like it's growning out of her body and is distracting whatever it is.
What a lovely interpretation of the challenge.
If it was mine, I might have concentrated more on the little girl and her shadow rather than including the whole scene, but it's yours and you made some nice choices here.
