I think EVERYTHING sounds good. Kick, snare, guitars and bass. Toms sound a little wack. Maybe a touch of 2-3k to bring them to life will work. Now for the main critique. The mix needs LIFE. It needs to be brightened up. I know a lot deathcore bands want their mix to also sound dark, like the music, but I prefer my mixes to sound like they are breathing okay. It brings out more definition in everything and gives it less of a muddy appeal. Overall nice work.
