I like this series - posing and lighting, exposure. The only problem I see with a few of these portraits including this one is that the focus is on the front shoulder rahter then on the eyes of the model where it should be... Perhaps you did it on purpose, but why?
[I could understand if the whole portrait was soft, but it is not the case here]
This shot is so amazing, i am seriously in love with this shot, there is just something about it, the composition the dof, the color, its amazing, wow, great shot,
