Good Job! The story was funny and your voices were distinct.
Things you may want to 'look' at:
The music and special effects got in the way a little, there were parts where I couldn't quite understand the vocals on the first listen.
Also, the main character didn't really react believably sometimes (he should be scared or angry but he still sounded kind of 'aww shucks' if you get what I mean), but that may have been a stylistic choice.
One other thing I noticed was that the bad guy said 'You caliente punta', which made me laugh because he was cursing in Spanish incorrectly...
Again good job, and good luck in the contest!
