Good quality and very well animated and the sound is good but since it is a test, going pretty post it in the "Dumping Grounds" (yellow garbage can or a yellow box with a white arrow on the top pointing down)

bloody

The animation quality is very good, sounds were ok, but the main 2 reasons of my low rating is that there's:
No Background: Just a division between ground and sky.
No Story or script: It's just a killing scene in which a mad man tries to kill a man.
No relation to christmas: About christmas I just saw a X-mas hood on the protagonist, plus we are in febuary :P

This is considered as a test, something you make to improve your ability of animating, but tests aren't whole movies, so please, if possible, don't post tests on the portal :)

Animation is overall good, but man... Do not post test on potral. It's too short to be a complete movie.

I like your art style, even though its not orginal, I like it, you should try to do more, like add more enimies! I like how creative this kill was. Keep working on it!
