There isn't a whole lot to say about this tutorial: 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.
