Zhiffy,
Really like this shot. The pose is a "moment" pose, not easily replicable. The shadow is unusual and adds to the off-balance feel of the shot.
Personally I would PP down the "edgy" route, adjusting colours and lighting ratios in post to go moodier.
The reason it does not shine (even though the shot is technically good) as a fashion shot is actually because the clothes say "casual" whilst the pose screams "I'm different". Hence why , having set up and caught this moment, I would PP it towards "edgy".
I visualise it this way: If that was Kate Moss topless in CK jeans and barefoot, in black & white, the exact pose (and shot) would be a winner outright. Thus indicating that the technicals are good to great but the context and element reinforcement could have been better synchronised.
Keep up the good work
My humble 2 cents.
