This has Potential!
You're character designs are really awesome, your music choice is great and your lighting effects are very interesting indeed. Might I suggest a couple of things to improve upon?
1)Facial Expressions - It looks a little strange to see a character yell FUCK YOU, I HAVE A GUN! and have such a neutral face. All you have to do is make another layer and use that to make different facial expressions, you don't even have to re-draw the whole character to achieve this effect easily
2)Animation - Your character seemed to be a little static and still like. Try to seperate the body parts on different layers, you've started to work on that but there is room for improvement, if you are willing. You might also want to use different camera angles, and draw your characters from different views, this helps in the animation department as well.
Other than that, you have cool characters and a nice story, although voice acting would be nice. Good luck on your future endeavours!
