I apologise for the size and inconvenient format of the file for screen viewing, but this "emotion tree"of mine demanded it, even though I shrunk everything as much as I dared to make it smaller.

There isn't a whole lot to say about it: obviously, it's a guide to the variety of emotions the human face can express, with as many pointers as I could think of to help you understand how the different parts of the face (and body) are articulated in connection with specific feelings. It was a fun tut to make, requiring more intuition and observation than research.
