The nice thing about this animation is that it doesn't even physically make sense for the cat to fly with its tail from this motion, but it's a believable feeling.
The problem with the tail is that, during its loop, it gains extra length then shortens, and it doesn't seem justifiable as a stylistic choice.
One other thing that got my balls all tied up is the hind leg; dat shape is weird mayn. The front leg looks alright, but the back one really is off lol
how long'd this take you btw?
