Life drawing - Sadness

I was interested in trying to convey emotion through the posing of the life-model, so I asked if she could show me how she sits when she is upset. I then proceeded to draw her emphasizing the parts of her body which are expressing the emotion, for example, the hunched shoulders and head in hands, using thicker lined and darker shadows. I didn't want to include the scenery around her (part from the chair she was sitting on) because I didn't want there to be anything that might distract from the figure and the emotion that the piece is conveying.
