Inevitably when you visit Tokyo, you spend a lot of time on subways and trains, moving around the mammoth city. I occasionally sketched commuters but with the seats set up as long benches, facing each other, it is hard to hide the fact that you are sketching someone if you are looking straight at them. Shoes are always a good option because it alleviates the stare factor.
In this case, I surreptitiously glanced at this woman wearing her mask on the train. She was absorbed in her cell phone so was unaware of me studying her. This drawing has a very sketchy quality because, for obvious reasons, I was going fast.
