Head proportion practice. The idea was to keep it simple but to put in enough information to be able to tell if something's really wrong. I tried to do them as quickly as possible because it's my initial reaction that I'm trying to improve. When I did linger to fix problems I tried to apply the knowledge gained to the next one. I noticed that I regularly put the jaw too low and I hope now that I'm aware of the problem I can try and change my habit.
