She looks quite uncomfortable and unnatural in that pose in those dressy clothes. You captured a very lovely expression on her face, but because her legs, with the bright highlights, are in the foreground, it is difficult to appreciate her face in the distance.
I love seeing a model used who is not the size of Twiggy. She is lovely, and the contrast in the colours of her outfit and the black background are very appealing. I love the pose, and her expression.
