The prospect of moving has not led to the most motivation or time to work on Blender things. I did manage to render these out over the last bit, and the tail pic is actually an update to the rigs I'll be pushing out at some point.
In all honesty, I have no idea how to rig a tail with the amount of precision I want, while keeping it user friendly. So this is a bit finicky, but if you're willing to put up with a bit of posing tedium, it will be a worthwhile upgrade.
