I really like the ambient sounds and growls in the beginning, did you make those from scratch? I'm definitely hearing improvement in your sound design. I've also noticed you're playing with your percussion and you are using filters a lot more. My favorite parts are right after 2:24 and 3:33, I like what you've done with the sounds in your transitions in these sections, and throwing in sub-drops always works. I've noticed you're using the Slayer generator for your leads. That generator doesn't offer very much control. Maybe it's just cause I've heard that thing so much (I think it sounds kinda cheesy), but you should try some other sounds. For a lot of electronic grungey basses or leads, the 3x Osc can be pretty good if you make some shapes for it. You are definitely making progress, you keep doin you!
