Robert Sawyer...sort of

Painted on my iPhone with the Brushes app. This was a quick one from the Darwinism Readercon panel with me trying to sketch the panelists courtroom-artist style. I only captured two of the panelists in the hour, a not very close rendering of Robert Sawyer--who was pretty serious through the whole panel, but he has the widest smile in all of science fiction, so I had to draw him wearing it.
