Good mixed with bad
Your animation is okay, you know. For example, the parts where he changes his pose and such, like when he grabs the stick. That was good, I liked that. But it was flawed. For one, the movement was just tweening it up and down, and you could see where his trousers had been cut off; if it weren't for that trouser cut off, I wouldn't have minded so much. For two, the door opening was just lazy, putting a black rectangle over it. It could have easily been fixed. As for the shooting, well, I think it could have been better if you'd flashed it white, not black, adds more emphasis.
There was also little plotline going on that I could see. He went and bought a staff, got shot, and the shooter gets shot too? Umm... maybe it's an in-joke between you and your friends, but I didn't get it.
I'll give you credit for the slight amount of frame by frame you did, but a lot of it was lazy. I did like the character design, though. You get a 7, and I hope you improve. You have potential.
