Thanks for the comments so far!
Walter, good catch on the different quality of light on her eye. This shot is for an assignment involving using a mirror to isolate a feature within the frame. So the shot is exposed for the reflected light hitting her eye from a taped-off mirror that was positioned off-camera. The light silhouetting her hip, chest and jawline is from the light positioned slightly above her feet. The light on her eye is the little mirror reflecting that light back at her. It's actually the same light on her shoulder in the first two.
