What should I improve on?
You need to smoothen everything.
You need to ease everything.
You need to make them all less stiff.
You need to make things that are physically possible.
You need to add more force.
You need to spend more time on an animation.
You need to only show us animations that you think are good.
You need to think about the laws of gravity.
You need to make the sticks bigger so its more recognisable.
You need to make basics first.
You need to spend more times on effects.
You need to stop switching the colours of the sticks.
I need to stop posting these kind of posts :P
And wth poppet? If you can't make a good punch, you can't make a good fight scene. Common sence, you should know that!
