You get no stars... I don't reward people who really.. really don't do too well on their presentations. Honestly, the explosion didn't make sense, and it just seemed to be rather poorly made. The animations and what not were pretty terrible. That you had no voices, but you had little animated sounds... It was just terrible. Keep trying, and when you've actually got something that you think is amazing you can come back, but for now you've got to make sure you don't have things that look this poor, and have people who always have their weapons out.
Um, could be worse, could definitly be better. To be honest, the animation itself isnt too bad considering this is the first thing you've made (This is the first thing you've made right?) but it feels unfinished, definitly needs more polish and effort put in. If you make an animation that lacks a decent story just for the combat and/or violence, which is the way this come across, it needs to have a much higher quality of animation.
Making fun of drugs is not the best idea.
