I've been looking at the drawings of Jean-Baptiste Monge who draws mainly with pencil, so I decided to use pencil to try to make the same markings he does. It didn't quite match his mark-making, but the look isn't bad. I want to draw old people and see if I can turn them into gnomes or elves. Monge makes them look really interesting.
My kids showed me a YouTube video of the elderly playing Five Nights At Freddy's. Those people have interesting faces and their reactions are funny, too.
