needs work
I can see why you called it a prototype, here are some things you can improve on:
1. when the dude hits the rail, he'd be in so much pain that there's no way that he would be able to form actual words, maybe have him scream or just roll around
2. I like how it's animated like the awesome series, but some people may be angry about that
3. get a better mic
4. make it longer and louder
Hope this helps
