Artitically, the jacket and floor draw my attention much more than the 7 lockers. The challenge was to take a shot with 7 of the main subject, and they are bland in comparison to the one jacket.
Lighting in the environment eas sub-optimal: I don't care for the way it hit the handles. Also, in resizing you've got "jaggies" on the locker doors.
It's a very nice shot, i mean it would be a candidate for a 10 from me, i love this kind of stuff. But: sharpness just doesn't seem to be there. Perhaps it has to do with the allowed image size. And also, i generally like the composition, but something seems to be a little off there. I'll put a placeholder 7 for now, but will come back another day to definitely adjust that. Won't go lower, though. =)
