I was feeling inspired by a trip out to the art museum... so I did this sketch of a memorable scene on my bus trip yesterday. A woman with a baby who was fast asleep stood through the whole trip.
I used to sketch on subways in Art School in NYC. I'd never do that now... so I work from memory instead. In his book 'John Sloan on Painting and Drawing' I was amazed to find out that John Sloan did most of his paintings from memory!
