I took a shot of the sphere that will become the head next to my old head (which serves it's purpose for sizing purposes).

i took the shot into Photoshop and first brought the Facial topology pic and imposed it over my old head. then i drew a basic kennedy face on it. from there i added the two blue lines, one i'll need to add for a mouth, the other for the edge of the mask.

after that, i just redrew the topology onto that face from a basic idea of how the face will layout. thus, it gives me a real game plan for modelling the face. Now i know where lines should lay out, which lines can flow easily into which and what edges i'll need to get rid of, etc.
