I can't be the only person who, when drawing characters and expressions, has the habit of making the expression I'm drawing. <|D I catch myself doing weird face contortions way too often for my liking, and, of course, it only seems to be in public. You know, in classrooms, cafes, quiet study areas, libraries. All the best places.
