Not bad honestly, could do some improving.
My tips as a fellow animator:
The easing and timing are good overall but u forgot that if u animate u have to remember that even if u draw something a lot of times you should keep it consistent with the proportion. If something is 10 inches it remains 10 inches unless an outside force does something to it, the only exception is if it's magic.
Another thing is that u also have to take note of anatomy, your character anatomically doesn't make any sense since a tail is actually a part of the spine at the tail bone,while yours is basically in the middle of the back. Unless it's some sort of mythical creature monster that defies physics I don't believe this
Overall this IS a good start to animating. You are VERY promising. Don't be down if you aren't that good now, I went through that too. Learning isn't a linear line.
