your pose and facial expressions very convincing. To me it looks like there is a threat off camera and your debating if you have to fight or flee. The only fault I would have (and this is just a general irritation) the outfit is a halter top, which means using a Bobbie pin should have able to get the bust to fit correctly on your chest and either cover up your bra or render it not needed.
Or if you do need to wear one, a flesh tone bra is much easier to conceal in a convention sense or within photoshop. I would like to say again that I do quiet enjoy the photograph, your a very good model and the costume is also really beautiful as well.
