Side view animation and jaw-based lip sync

[Ben RiverRiver]

I'm trying to animate a skeleton character with face and body tracking. The character has been supplied to me by an illustrator as a flattened Photoshop file whch I'm choping up to create the differecnt body parts. My first issue is that this character is drawn from a three-quarter side view. All the tutorials show setup for a front view so I'm not sure if I need to alter something here. 

 

Next, the mouth movement should be all based on a swivel motion of the jaw bone. I would love to be able to lip sync this but again the setup is different from everything I've found on tutorials. I'm wondering if the nutcracker jaw is the answer here?

If anyone is able to point me in the right direction I'd be super greatful.

Your rigging for the 3/4 view should be similar to frontal view. The only difference would be to arrange the layers so that the arms and legs are in front of and behind the body and head logically. 

Regarding the jaw, yes I'd start with the nut-cracker jaw, arranging the origin where the mandible attaches to the skull.

Good luck!
