Lovely image. Just enough light on the right side of her face, good separation of her shoulder from the background and a beautiful look from the model. Nicely done.
Maybe it's just my monitor, but I'd like to see enough light on her neck so we can be sure her head is attached to her body. I'm looking at a face floating in space. I don't care much for the tilt, either.
Woe, amazing portrait. Very nice shadows playing across her face. I like the way her head is tited and leaning slightly. THe glimmer in her eye is very nice. I also like the pearls around her neck.
