Well..
I really didn't like it, it was pretty stiff and the characters moved like robots. One thing you must remember while animating madness, is physics. Life like movement. No one would be lifted in the air to be shaken off of a pistol. The human body madness was just "bleh"
Now I shall judge each part...
Part 1: It was very very stiff. And shotgun bullets do NOT spread out like that. And when someone fires a shotgun with one hand, there WILL BE MORE KICKBACK.
Part 2: i guess it was okay, I couldn't really tell what was going on..
Part 3: Well it was waaaay too jerky. Very very twitchy.
Part 4:I guess I could call this the stiffest. What the hell. When shaking someone off of a gun, the body is supposed to move and it would be impossible to actually lift someone in the air over a gun. The shading was kinda too much and why would a plane be flying that low?
Part 5: Again too fast.
Part 6: What the hell? Human body madness? The fbf was okay but still kinda weird.
Part 7: Too short
Part 8: too short!
Overall I think that this was severely rushed. Next time take time on your animations to perfect them. Start something and finish it. Take some time to watch the movements that krinkels uses to perfect your skill
Good luck on any future projects.
