I understand it's unfinished so I'm not gonna go into criticizing the parts with missing items. However, there were times where the frames didn't follow in sync and certain things would disappear a second before everything else in the frame did. The sticks also changed size whenever they made quick movements, only slight but still notable.
As well you also have to keep in mind that these are just stick figures you're animating. So putting their "head" around simple shapes and colors doesn't help us depict that a stick figure is standing there. To me I couldn't tell a couple of times if that was a stick figure or just a random black circle. With stick figures you gotta make better angles to help better depict what your character is doing.
