I liked it, the animation wasn't what you'd see from krinkels or any other big guy, but it was good enough to make it enjoyable :)
The only thing I didn't see that should've been in there were blood splurts from wounds, blood splatters on the walls and gun shells.
Also the reaction time of the enemies seemed kinda delayed, like when the protagonist came out of the elevator, the two guys behind him kinda just sat there, even though while he was focused on the other guys, they could've shot at, or shot, him.
The only other thing I would say needs improvement is your camera movements, and when the bodys fall, the don't bounce like a human body would, they seem kinda robotic in the fashion they fall over and that's it.
But either way it's a good madness day cartoon :)
