This is really dope man :D and love them bitcrushy artifacts. Something you might love to is Kilohearts ringmod(free). One thing you can do is actually turn up the bias button which essentially turns it into amplitude modulation which is just a fancy way of saying really intense volume modulation. If you then set it to sidechain itself in the plugin then the amplitude modulation rate will be synced to the wave cycle of the sample. This will actually make each wave cycle more clicky as it is slightly dipping the ends of each wave cycle(something present in the skrillex growl- the clickyness I mean).
This obviously has all the processing hidden within the macro controls, and 100% the point of my statement is "this is awesome" but that'd be cool if you augmented that initial opening transient so that it wasn't so reminiscent of all the other growls that people have been making...but im not recommending you do that for you, i want you to f around with it and post results. Like strictly mouth made sounds, processed with a similar mindset as when you're processing a growl, but really capitalizing on the fact that you've mastered the craft of mouth growls and creating a new kind of niche sound. I can do it myself but you have more drive in you right now than i do. All i can say is that i make growls that nobody has done before, i do nothing with this skill, i hope you get a lot of love from other producers who love producing but have no inspiration to do it anymore.
