These are sketches I drew 1 to 2 years ago in various doctors’ waiting rooms . The third image is a combination of waiting room and subway. Drawing on location is a bit tricky because things never stay still. The moment I start drawing a person, said person moves even though he was staying still before I started. The other tricky thing is drawing people without them noticing you. What I do, is that I will look in the general direction of my subject but not actually look at it. I will steal glances at the subject to make sure I’m getting things right, but generally use my peripheral version to draw…and also draw from memory.
