Future Animation Related Tutorial POLL (Patreon)

OK guys, so believe it or not, we are just about done with the Procedural Texturing Series.
After the next month, I plan to move to the 3D modeling series. BUT, before that I will make a short detour into an updated Animation series. This will include the "much requested" facial rigging tutorial, updated rig, IK, and weight painting tutorial for 2.81, and creating advanced rig controllers for animation.

What are some animation related topics you'd like to see explored more thoroughly during this detour?
