I am disappointed.
Hm, some constructive criticism:
The intro is too long. Maybe you should present the characters while there is already action. Pause the movie shortly and let the names appear, that would be cool. Then, the sound quality is very low and should be improved.
Also the animation was rather not fluid, but I understand you are a beginner.
But what I cant understand is the aimless and boring story. There are nearly no jokes, no tension nor any action besides much too loud shootings. And everything runs in a speed of a turtoise. You should really make the movie faster and more interesting.
