I really like the fact that this one is off cetner. Gives it a nice balance against the buildings on the right, and it adds to the feeling of the subject turning. Though I would have liked the rails on the right to be as sharp as ones on those on the left. Just a personal preference I guess
So many complaints about the off centeredness... well... I actually LIKE how its framed... having it off-centered gives the symmetry of the geometric design more impact... it also fits with how she is 3/4ths turned to the right... and (with some more interpretation...) how she is alone... its a great image.
