Something about the way the girl is sitting and the lighting make it look like she doesn't have arms. Also, without the title you don't know that she's waiting for a bus... she could just be relaxing. Perhaps adding the bus stop sign in the foreground if one was available.
I find this uncomfortable to view for two reasons. First the foliage at the top competes with your main subject, maybe cropping that off might help. Second the slope of the wall just feels awkward, again a crop would sort that problem out.
The shot is quite out of focus and there's too much sharpening going on. Maybe the wall was too high? I'm not sure, but the composition isn't great. I gave it a 4. It's a good shot though. Oh and the contrast works quite well.
