I don't know which I actually prefer, the location or the model: eh, I'll just say both are captured perfectly! Great pose and I like the incongruity of the rough and tumble urban background (a place not entirely friendly to bare feet and bare skin, and yet there are bare feet and bare skin.) The contrast is intriguing in that way: it follows a kind of dream logic, which I suppose this type of photography excels at: hmmm...dreaming with a camera...there's a story idea in there somewhere.
I tend to go for incongruity. OK...models in nothing but underwear never hurts either, but incongruity really grabs my attention. I guess maybe that Liberal Arts education is starting to pay off. Or something.
