Some Low-Poly Face Modeling Tips For Rigging

Here are some Low-Poly face modeling tips I created specifically for face rigging. Hope you find them helpful.
cheers,
Nate

Rough Organization of Process
1. design phase
2. lattice retrofitting
3. reference edge loop compare to wires of lattice edited
4. removal lips, removal eyes
5. create refined lips and eye lids
6. insertion of lip and eye proper loops

Explanation:
1. make side and front views
2. start from an exisiting face model you created.  use lattices to fit face model roughly to images.  Each time were done using a lattice (ex for jaw vertices) we can delete history of mesh and create a new lattice for say the forehead faces.
3. draw in where the major problem area edge loops are example Jaw, and neck.
4. select inner mouth face and inner eye faces and remove them
5. use poly spheres to construct new lid.  use torus to construct new mouth. 
6. scale the eye lid and lips to fit mesh.  remove extra faces and connect them to existing face.

Helpful hotkeys modeling for rigging
1. xray toggle
2. toggle view selected
3. edge smooth
4. vertex merge
5. key to go to front view and perspective
6. key to go to side view and perspective
