I don't like clones...but
This was alright. Not great, but not terrible. I'll pass it, but you have a lot to work on.
First - Animation needs to be faster. Right now it's too slow to hold the attention of people. Work on pacing.
Second - Audio. Something more than gun shots. Use background music and voices. I know madness doesn't use voices, but don't try to be a complete clone. Add some voices.
Other than that, this isn't too terrible. Just work on those things and you might have a good movie for madness day.
