Love the setup, Love the lighting, beautiful girl... not in love with the pose... would like to see the eyes more in focus, and her eyes positioned so you dont see so much of the "whites" of the eye... also having her tilt her chin up a tad so the brow bone doesnt cover a portion of the eye... those minor changes and you would have a stunning photo.
Wonderful portrait here. Very uncommon pose, the composition works great for me. The expression of the model is great and the DOF perfect. Maybe the hair on the bottom right is a bit distracting for me. Nice job.
