This tells a story, or at least makes the viewer very curious to know her story. There is something sinister about the surroundings, yet she looks happy. Incongruous, which is always interesting.
This is only the second image that I came across to vote on, but I bet that it will be one of my top few. When it popped up, I almost immediately felt a sense of waiting. I think that you could use a bit more contrast, perhaps a curves adjustment, but the composition is terrific. The position of the girl draws the eye into the image to inspect all the interesting elements you included. Nice toning, but I think I'd like to see the darks just a little darker.
Let me start by stating that I am only learning about "street photography" myself, so take this crit with a grain of salt, but IMO this seems to lean toward portraiture. Just curious: was she unaware of the fact that she's being photographed? Feel free to PM if you are inclined. (5)
