Facial Animation

For the facial animation for this character I began by working on the jaw, as I imagine breathing relatively heavily would cause the jaw to be the main focus of movement.

Below is just an image of how I set up the jaw rotation tangents; at first I had the tangents set to spline, but i needed the mouth to open in a linear fashion with no slowing or speeding up. After that I wanted the mouth to close at a slower rate. For this to work I set the first key to have a linear out and the second key to have an edited spline out.

I then worked on the lips and cheeks, making them inflate, deflate and constrict at the right times. The eyelids eyebrows were next.

Here is the facial expression so far. I am happy with it at the moment and don't think I'll need to change a lot, but feedback might change this.
