I can't say if it is good or bad or how to improve it or even if it needs improving. It made me extremely nervous and I felt like going out and killing something. Is that the reaction you were trying to accomplish, to create an awareness of violence that lies in everyone?
Sorry, I really don't want to cut it down. I just didn't care for it. If you like it, that's all that matters. However, if you want to sell it or get some praise, you may have to listen to what other are saying. If I were you, I would save it and put on the back burner. Start on something new from scratch. Later you may come back to it and work on it some more. Maybe you will change it to please more of an audience.
Good luck on your creations.
