Stiff, and choppy, but not the worst I've seen.
Ok well for starters, it was stiff, choppy, and badly animated. You didn't animate the bodies at all, it was just the hands. You basically had walking statues all over the place. Add in some rotating of the body while falling and shooting, and don't animate the head along with the body, give it a bit of bounce in occasions, and you'll be fine. Okay so after like, a few more rooms, you see the guy with the grenade. Um, several issues with this. For one thing, wasn't the grenade thrown at him? If so, why didn't it explode? I noticed that the pin from the grenade wasn't taken out, so that must have been the case. Okay so he throws it in a room, but then it gets thrown into another room. Well, give your guards a sense of intelligence, they should have thrown it in the room it just came from.
But anyways, this was a really bad thing that you did. You made an explosion, but it wasn't shown, and when he got to the room, it was just a bunch of bodies laying there with bullet wounds. Well, it would have been better to actually show this, rather then just pan to it, and not be so lazy. And also, explain to me how a grenade gives bullet wounds.
Well that's pretty much it, however, I'm very surprised with you.
You used the correct hands.
You see, normally people don't use the correct hands, they either have two left hands, or two right ones or they're just all messed up. I'm so glad that you're smart enough to know your right from left, and for this, I respect you.
Plus the animation wasn't the worst I've seen from a beginner, just add more animation, with the feet and body and stuff, and you'll be fine.
