Very good beats.
it gets a bit repetitive, but the main beats and bass are solid, so it's not really painful or anything. there's an odd voice at the end and begining, which might be going on the whole song, but it's hardly audible for most of it, and it seems out of place at the end...
other than that, most of the riffs are really good, but I don't quite understand why you put it in miscellaneous. it seems like a pretty solid Dance or Drum N Bass song.
what program(s) are you using to make this? If I had to guess, I'd say Fruity Loops, because I think I Recognize the slayer and Bass Punch.
4/5, very good and enjoyable, but could defintiely be improved.
