I can't tell if you're going with a blackmetal aesthetic. But some comments on mix. Drums are buried. Take down those guitars by however many dB it takes for them to become clear, and cut the 250 hz and below on everything that isn't drums or bass. I might even cut up to 28 hz on the bass just in case, to make room for drums to cut through.
Your guitars could use some cleaning with a multiband compressor. I think it's ChernobylStudios, or maybe FakeSmileRevolution that does a great few tutorials on just getting an aggressive guitar tone. Works magic on vst guitars.
Now speaking of your everything, the velocity and expression values are there for a reason! No one wants to hear a double bass roll like Skyrim freezing in the morning. Okay, maybe some crazy people do, but I am not one of them. I for one don't want to hear that. It means I have to go and edit values. I hate editing values.
Anyway Misha Mansoor does a great tutorial on youtube for that. Writing drums.
The velocity on your lead sounded the same throughout. I would change the chord thresh value some, turn on a humanizer. I actually can't tell if that sounds like RealEight or Shreddage II. With Shreddage II you're more likely to have that dead on sound of being locked into the beat just because the way they snap into the DAW, but RealEight is just as bad about sounding shitty if you don't use the keyswitches. Take note, use the keyswitches, set up some funky velocity crap. Figure it out so that it doesn't sound like pitching up and down the same articulation of a different note. Been there, lol.
Otherwise, hardpan your left and right rhythm guitars 100% L and R respectively. Leads I would pan anywhere between 13 and 33 percent L and R, with a pingpong delay between the instances to play into the other channel. Make sure to humanize all of these separately and randomly so that they don't sound the same. Use different amps and cabs for the L and R so they don't sound like you just copied the same track, etc. The lead can be made more compelling by playing with 3rds and 5ths every so often.
Beyond that, not really a whole lot of critique. The song isn't overly long, it's not poorly written. I feel the leads may have been lazy, but maybe you just aren't very familiar with the software like I was when I first started mixing E guitars. Personally, I like to do e guitars and synth leads. But this isn't bad at all. Learn your instruments a little more and see where it takes you! :)
Thanks for coming out to NGUAC!
