WOW what a captivating face! I think the blue is too bright though, seems to compete with the face. What would it look like more muted? Wonderful lines too - I like the way all the lines tilt one way and her face tilts the other.
This is a charming portrait, very suitable for framing. The lighting and composition really enhance a beautiful young lady. However, I don't think it's a shot suitable for this challenge. Because you chose to leave an already busy shirt in color, it draws the eye away from her face and, most importantly, her eyes. I think all b&w would be perfect. Just my opinion since I can't vote anyway. Good luck.
Not bad, a different composition or even a different photo would've been more appropriate for this challenge, however. As it is, your attention is pulled to her clothes, but her face is where this photo's strong points are.
