I don't know why... But I almost get a creepy vibe from this. Like something awful is about to happen. The calm before the storm, so to speak. Orrr I just happen to watch too many horror movies. xD But this truly is a lovely picture. I love the contrast of the red coat and pink shoes against the background. It wasn't even until I read the comments after seeing the picture that I noticed the blue, however. Darn!
I really like this the only thing I would do to it is try to make the bottom of the streetlight less blue, it kinda draws my eye away from the center of focus (the girl) Maybe you might edit just that one part to black and white?
Love the shot, not sure if you're into PP or not but if you greyscaled the entire shot then selective coloured (masked) in the red jacket it'd look realy great too. I found the blue garbage can in the background distracting
