Tough Loveby
UbersteinyComment: Okay, I'm going to be critical here, only because you have real potential. You did not reach even your current potential here.
I'm almost 99% sure that you were dinged becuase the chains in the picture weren't really sufficiently part of the composition, or part of an implied idea. Yes, I know, you can tell he's handcuffed, but the idea of "tough love" doesn't represent chained, and then the literal representation of chains isn't really clear in the picture.
Think of it this way, if a paying client asked for concept photos that included chains, would they toss this or send it up for consideration?
Personal preferences:
You should have been bowing, face down, with the handcuffs in clear visibility right in front of her feet.
Not everyone is meant to be a foot model, her feet are pretty wrinkled and her heels are a bit cracked around the edges. Should have smoothed them out, or used fishnets to distract. Including more leg would make this more sexy, feet aren't sexy (well, to most) but legs ARE.
