Distracting.
The background at first looked promising of setting the animation aside to a different and more contemporary version of stick battles, instead it wasn't. It simply got in the way of the transparent-headed stick figures and distracted the fight itself.
The characters themselves did not show any real show of physics or bodily control, making this quite unbelievable. I know, I know, it's a stick fight and anything can happen, right? Well, one thing all good stick animations is fluency and correctness in the ability of human function.
Spend a little more time on making the sticks look more realistic. It's too hard to keep track if there's no distillable differences.
Good luck in the future.
