Is that Autogun/Ogun? Sounds familiar. You're starting to see how little differences go a long way. Try EVERYTHING once. Delay on a kick drum... Reverb on the master... If people say not to do it, do it once and see why you shouldn't. I'm not a big fan of the 1-2..3-4--- pattern, the one at 3:00 but I like the main pattern, at 2:15, 4:00. Changing up the bass a a few times would be a good variable. I found the lead suprisingly easy to listen to. Don't forget to take breaks cause your ears get tired and tell you to do weird shit.
