You have a great inspiration on Xtrullor. The one thing is in 1:21 that cut of drums were so strange for me, but everything else is so good. I recommend don't turn down all the volume by using sidechain, but that growl at 3:00 sounded so sick. For your next coming songs I suggest you to use nice FX's with a little bit of less volume and a small quantity of effects like reverb. It isn't so bad to be your first upload, I hope you succeed as a music producer, nice job!
