Good character design is essencial to readability in the face. We'll look at the principle known as "The Golden Triangle" as a way of achieving such design. Well also look at the game Team Fortress 2 as an example of using overall character design through shapes and silhouette to easily clue in the viewer to who the character is.

Great visual notes here.
