That was a great animation but some errors and other things.
-Fast FPS.
-The dudes pass by the wall when they are comming from a door. (Make a shape with the same color of the BG and put in the side of the wall.)
-Some other things, like no foots, no gun flashes sometimes, but you say that on the description, you don't have to fix it, just don't do that errors on PT2...
