Well, no one can deny that this is definitely confidence - no female can, at least!! ;)
Let's talk technical aspects... Focus is good, but exposure is tricky... Your choice of a shiny white fabric is interesting. This would be something that I personally would shy away from to avoid overexposure, hot spots, and overpowering the main focal point of the photo. You make it work well (on my monitor it looks fine, but on a more brightly calibrated monitor it could easily appear washed out), but I think your photograph might have been better served with a darker, less obtrusive color. I've always found that bright colors attract the eye more than earthtones, and the most crucial element in your photograph is the only subtle color in the entire shot! The bright colors and textures of the fabrics contrast so much with the skin that it almost makes it seem like two entirely different photographs layered on top of each other. In the future, I would suggest deciding what you want the viewer to focus on, then eliminating or adjusting any elements that might upstage or detract from that focal point.
As fas as composition goes, there are some great curves and lines in this shot, and I love that everything seems to draw my eye to the center. The only problem I have is that what I feel is the focal point of the photograph lies nearly dead center, which makes the shot seem less interesting than it could be. I would suggest moving the camera view up just a few centimeters, eliminating some of the unnecessary fabric and bring more of the chest, you focal point, into the frame.
Now about the challenge theme.. I really enjoy this creative take on the challenge. This isn't something that I would probably ever associate with freedom, but now that I see it, it definitely makes sense! A lot of commenters said that they think this is the opposite of freedom.. I think perhaps they misunderstood what you were trying to say with this picture, which is a risk that artists will always face.
Great job with this picture!! *I* liked it, at least ;) You've got some fantastic photographs in your portfolio, and I look forward to seeing more of you work in the future. If you have any questions or comments, feel free to e-mail or PM me!
Freedom, confidence, or constraints...I'm not seeing the relevance to the challenge here. The jacket is overexposed, drawing attention away from way should be garnering attention. The colors are nice, but the cropping keeps the picture from telling its story.
