Reminds me of Mary Tyler Moore.
her smile is nice but I can tell she was uneasy in the photo from her eyes and the photog rushed the shot, too much overhead lighting washing out the backarea of the subject. I'm guessing this was early in the shoot. her hand position is showing that she was having a hard time with relating and trusting the photog. also could have used the beautiful elipse in the background more by bring the camera more to stage right and framed the shape better.
Gorgeous, sexy young woman.
This photo would have been more effective if the model was looking more sultry and less "smiley"
The body language!
Very nice shot. She has a gorgeous smile.
