I've been sketching a lot of people lately, in waiting rooms, on TV (as above) and at life drawing co-ops. (See some sketches from my recent visit to the Altered Esthetics costumed model drawing night here.)
I love changing what I'm using to get different effects. Above I was working with a Faber-Castell PItt Artist's Calligraphy pen.
I'll have more people sketches up this week.
