joint based facial rig for bear. Flexi lip controls I achive using curves. Tongue is quite limited since it's only FK. We could use ribbons or curves to make this more flexible. Around the eyes there are curve on the brows, but again not much flexible, so we could use more curves there or ribbons to get more control over the cheeks and brows. The nose and nostrils there are simply joints constrained to the controls with translate, rotate and scale so sometimes simple solution will do the work.
