Lighting and camera set up

I created a rough layout of the scene. Which may stay that way since I'm mainly concerned with the animation. Anyways, the rough is good enough to allow me to set up a light scheme.

I'm using a lot of light linking, as the zombie characters have "negative lights" on them. This is because, I want their sunken in stomachs, to stay defined.  I also have lights in their mouths to tone down their all white teeth. 

While I'm doing this I'm still listening to my audio track, that I'll be animating to. Recently, I learned a neat way of figuring out the jaw's openness on each word. Placing your elbow on a table, with you closed fist pointed towards the ceiling(palm facing your face). Rest your jaw on your fist, kind of like Rodin's "the thinker" Then say the line at full speed. You'll feel your head bounce back on each wide jaw shape. You must say the lines at full speed, to get an accurate representation though.
