The animation is very strong. A few things for improvement:
Choose a better background or get rid of it. That background does not make sense nor look aesthetically pleasing. For a simple animation like this it would have been better to have no background at all if you're not willing to put in the effort to make it look nice.
Also, I would have a clear ending. It seems like it just ends in the middle of the fight.
As far as animation goes it's strong work, though!
One of the best stick animations I've seen in a while
why thank you
