Ooh nice animation!
For the eyes most people close their eyes faster than opening them. So, if you want a natural looking eye blink what I like to do is:
1. Open eyes
2. ¾ closed eyes
3. Closed eyes
4. ½ open eyes
5. Overshoot open eyes
I hope you understand! Have fun animating!
i like when the tail gets a small bouncy effect after it stops moving kinds like this
1. swoosh down
2. stops, but goes a little upwards
idk kinda like that lol
asides, this is really good!!
