Tail- Follow Through Refrences

So I’m starting to add in some follow-though in the tail, and it looks much better already. I’ve obviously got plenty of references, with all the actual squirrel videos, and I have allot of stills that I originally studied for the way squirrels run.
  I would like the tail animation to be quite fluid and flowing. I will also exaggerate the movements in order to get the strongest poses possible.
 In terms of squirrel behaviour, they have good control over their tails and use them primarily for balance. and also seem to twitch them when thinking. (Mostly when they pause before jumping, etc.)



There are also loads of animation exercises on the web like this one.
