I'd be interested to hear her story Tommy. To be honest though i think if she turns out to be a model pretending to be a prostitute i'd be pretty disappointed in the shot as it states to find someone in your part of the world and tell their story. I'd kind of think it was DNMC then really even though it is a great photograph whatever.
A beautiful model and a great background. I'm not much of a portrait pro, but I can offer some first-glance critique... her fingers on her left hand appear cut off at the knuckles and a vertical crop may focus the attention on the model more.
