Face Rigging Help - November 2022

For my final year of studies, we were all placed in groups to produce a short film. We started production in Term 1 (February) and delivered the final film in Term 4 (November), we were all tasked with helping in various stages of production during each of the terms.
These Face Rigs were produced for a different group than my own, the group asked if I would be willing to create the face rigs for their characters, as they themselves were too busy with their film's animation and environments.
I was only responsible for the face rigs themselves, the body rigs were made by the group's own members (I did provide feedback and suggestions on cleaning up the body rigs). All the rigs were produced inside Blender.
