A well placed dot

Ro and I were working on a self portrait project when he decided to draw a picture of me as well. He would study me closely as if he were really trying to analyze the form of my nose and then he'd turn around and put down a dot on the paper. It really killed me because he looked as serious as any figure drawing student, so I kept expecting him to draw something more complex. However, it was a very well thought out and well placed nose dot.
