So...
It's obvious you worked hard on this, so I won't just blam it and say it's crap.
Try improving your walk cycles and backgrounds, that'll make the movie easier to watch. Going from inside a house to all white = bad. And it felt like the two dudes in the fight-scene were letting each other take turns. Also, in the sniper scene, where the dude has the speech bubble saying "watch out, he has a gun!", the speech bubble was redundant, we can see the gun. Also, the noise you recorded for when the bullet hits him is...hysterical. Which you don't want. There's plenty of free sounds on the internet, I'm sure you could find something to replace it.
On the upside, when Sarough shot the blond guy in the head, that little spot was terrific.
^^ Not trying to be too hard, hope you improve with your animation.
