Sounds like there might be some tuning issues here and there. Also, drums sound very thin and synthy. They're panned well enough, but could use some more FX. Solid riffs, but it feels like it's really missing a solo laid overtop at some point. Mixing on the guitars is also really muddy. Also quite hard to hear the bass. At some point it starts to sound really garbled to me. Drums also seem to be hiding in the mix a bit. Compress them harder! The cymbals are only really audible because of the frequencies, I feel.
I can also hear where it sounds like the bass and guitar are mingling and clashing around the 200 Hz range. Need tighter mixing on the guitar.
The whole piece just feels like it's not tidied up. Sounds like a backing track. Ending was well executed though.
