I have said before that a successful portrait/model shoot is part dance and part acting: dance skills allow for relaxed and beautiful poses, and acting ability allows for expression and emotion to flow unhindered from the subject. Grace (with whom I worked with yesterday) has both, and I think we got some good results. All I had to do was suggest a scenario and she found an inner dialog and a real expression to go with it.
