(Removed two of the three lightbulbs from the track lighting in my room, put the middle spotlight just in front of where I was sitting with a small lamp on the floor behind me. Hung a dark blanket behind my seat)
The eyes do not look as crisply in focus as the strands of hair and the ear. The lighting of the face seems a little too flat and strong for my taste. The model looks just a little uncomfortable. Nice tilt of the head, placement, composition.
Your light is too flat. Try moving you light sorce 45 degrees to the side and it looks like she is flipping off the camera, which would be ok if her facial expression matched the gesture.
