I like Smurfs because of its human representation in simplified and exaggeration form. With this I can spend more time to explore the form of facial components.
Perspective - Smile
Perspective - Angry
Perspective - Shock
All facial components are constructed using NURBS: sphere, cone and torus.
Parameters that enable facial expression:
Eyeball (size & position) - translate/ rotation/ scale
Pupils (size & position) - translate/ scale
Eyelid (shape) - sphere span value
Eyebrow (shape & position) - translate/ rotation/ scale
Nose (size & orientation) - rotation/ scale
Cheek (shape) - translate/ scale
Mouth (shape) - translate/ rotation/ scale
Lips (thickness) - translate/ rotation
Chin (position) - translate/ rotation
Ears (orientation) - rotation
