Haha I feel you man. We're a new band and this is out first real attempt at a song. I say we lean more towards metalcore but people have been saying deathcore, hence me saying both . To answer your question the only breakd0wn in the song is at the end.
I think it sounds fairly terrible. But hey that's just the collective thoughts of everyone in the world.

1) this forum doesnt usually approve of much modern "core" stuff
2) pretty sure the first two guys were ****ing with you dude
3) this is the forum for original songs https://www.ultimate-guitar.com/forum/forumdisplay.php?f=51
4) this is really bad man. totally offbeat, and the guitar tone has no balls to it at all. also, not deathcore at all

sadly this is probably one of the nicer responses youlll get out of this forum
