Waiting to be Chained

I love this shot. Everything about it is appealing. The background is provocative. The title says a lot. The expression on her face is amazing. I have tried many ways to photograph this pose just right and you have really done it well.
I love the models lines and her overall look. Her feet may also be the most sexy thing in the entire shot. The mood is playful yet very exciting.
This may be the sexiest photograph with only implied nudity I have seen in years.
Since this is a critique I will put a suggestion more pout to her expression and lower her shoulders a bit.
