NOW ADD BLOOD.

Well, it's better than stick figures anyways. The thumbnail was kinda clickbait, which is something you should avoid heavily. I will say I do like the flow of the animation and the sound effects, it certainly has more effort put into it than some of the submissions on the movie portal. However, be sure to improve on art styles and designs.

Pretty ok as far as animation goes
Work on the art

This is pretty good.
