Beautful Gesture drawing from the train

I drew this very quickly with a sweep of my pencil as far as the body is concerned SHe was standing this way for an instant and I managed to nail this beautiful pose. I was absolutely giddy when I inked it. It's moments like this where I say that drawing live on the subway is the REAL "LIFE DRAWING". No way could I get a paid model to pose like this with so much natural grace and personality.
