One of the advantages of taking public transit to work is the downtime.

I finished those top two very quickly, inside of two or three stops. The bottom two are both unfinished. I spent more time on the guy with the hat of all four sketches, but he just wouldn’t stay still. The balance of the outline shape works well for me, though. I had enough time with the figure whose back was to me to at least finish her and her immediate surroundings, but as you can see, there is a rough-shaped profile behind her of someone who was there for just one stop.
