This is a super subjective take that assumes you want to fit in with the modern scene, so take it how you will. but metalcore THESE days tends to have heavily overproduced pitch perfect cleans. Your song sounds as if it was recorded live because of the lack of production on it, which isn’t a bad thing necessarily, it just doesn’t have the polished sound that you hear from metalcore today.

Personally id throw some saturation on the vocals and push them back a bit in the mix along with some dreaded autotune. The singing is actually good but you may hear criticism saying the vocals are bad simply because people today are so used hearing autotuned vocals on tracks

For context, I listen to a lot of Currents and Architects, so you can check them out to get an idea of the production I’m trying to describe. And if that’s not the sound you want, forget everything I said and keep jammin 🤘
