Bass needs to be a little bit more diverse..
Infact the whole thing should be shaken up a bit, haha. Also, assuming you're using FL Studio, use the bass thats in the Slayer, I think you'll find it works better, haha. Nice try, you'll get better as you go, I'll wager. Good luck!
3/5. Replayability 7/10. Keep your head up! :D
