So, I like this shot. It seems like there was some heavy sun out there but you did a good job not overexposing any part of your subject. I would have used a smaller aperture tho (maybe 6.3 or much higher) for deeper DOF. The face of the girls is a bit soft on focus. For some reason, I don;t like that she is posing for someone else. It definitely seems as tho she is.
Anyway, good stuff!
Hope this critique helps.

Technicals: The lighting is good but it feels a bit intense because of her squinting. The color and detail are good but her face could be sharper. With the amount of light you had available you should have shot this with a much smaller aperture, which would have helped produce a sharper image of her face.
Subject/composition: I like the choice in subject with her instrument and medal included. The composition is also good. There's some space around her yet she isn't in the center, which I like. The background isn't distracting or anything like that but there is some detail there but that detail doesn't tell me anything more about her. In other words I think maybe something with less features should have been used or a background that in some way told us more about her or her music. Unless of course she's a street performer! In which case scratch the background comment. :P
Verdict/Summary: I think if the issues I mentioned were corrected this would have been a 6+ scoring image, IMO.
First Impression: Congrats to the winner
Composition: Very good composition IMO, with the girl in one of the thids, the accordion down and the free space on the left up. The BG is OK.
Subject: Meets perfectly the challenge. Cute girl, but with too much sun to her, so she cannot have her eyes wide open.
Technical: The light is too strong (maybe midday?) and that creates some technical problems: the colors are a bit washed and need more contrast for me; the shadows are too large up-down in her face. And the focus is a bit off her face, it's more on the instrument.
Improvement: Make the shot sooner or later in the day (if the girl is available, LOL).
Summary: A very good composition a bit scored down for the problems on lighting.
Not bad but somehow the girl is not as clear as is the harmonica and the wall behind her, did you blur her or is this taken at a long shutterspeed? Anyway, she seems out of focus and it´s definately hurting the shot.
