the growl is good but it needs some mastering. it overall sounds quite mono, you might need the stereo enchanter to balance the panning.
Now for the general bass, not the growl bass, it sounds weak, or there was none (?). Maybe you should start layering the bass as well. And btw, the kick n clap at 02:02 was overwhelmed by the bass and synths, the clap needs to be louder
