Very accurate to the original! However, if I had to be nitpicky, I think the @4 in the melody with the envelope in channel 3 and the pseudo-echo for it at 1:12 sounds too abrasive. Probably @14 would do in place of that, and the envelope could start with @0, @13, and then @1 and @8. Also, the entire envelope in channel 3 itself could be a tad quieter like in the original song. The @4 in channels 4 and 6 is also a little too loud and could be quieter too. The scream's pitch isn't quite accurate either, but I could let that slide. Hopefully you'll address all these nitpicks, but otherwise, it's still awesome.
