Life class drawing

Since I arrived late (well actually they started early) I had an unusual position for this life drawing. Only towards the end of the session I noticed the other artists in view and decided to sketch them in. It must be quite strange to be naked and surrounded by people drawing you, and I'm not sure it is for all. However most of the models seem to find something in it more than just the money. There is a serene but intensely concentrated atmosphere in a life class that does not happen in most people's lives, and it is quite addictive. I think this could make an interesting painting.
