Only one, today (the rest were gestures--1.5 hours of gestures): a modeled drawing of the face. It took me more than an hour to do this. Which surprised me a little. The left eye, nose, and area around them I spent the most of my effort on. They were also the last things I spent my effort on. After the right eye got cockeyed, and the lips fell too far from the cheek, I spent the rest of my effort on the parts I hadn't botched as much.
