Excellent clarity in the fine detail and a good capture of the child's expression. Great tones and B&W works well in this situation.
Most voters will likely "get it" but some may just think it is another kid picture.
You might consider cropping it closer on the child to highlight her. She is the main subject and much that is around her adds little to the composition.
Looks like the lines of the bricks and the top of the fence are slightly off horizontal by a third to a half a degree. In that situation you should rotate the image to make them perfectly level.
nice focus. You could have dressed her in shabby clothes and made her look homeless. that would have really driven the point home. The Flash was a bad call, a street light would have looked more convincing. Black and white was great call. I gave you a 6.
