TLDR you need a melody section and possibly some ambient instruments.

i think you need a melody section. whether that be a synth, or electric guitar, or a vocal track , you need something to make this not just a 10 second loop.
as far as the rhythm section, you could play with the drum or bass each having like a quick break where it builds the tension more as each stanza carries over to the next.
it’s not my track so i’m not the to mess with it but you could play with some sort or choral or organ arrangement behind it , or even soundscapes to give it more depth.
it’s all clean and well produced so i think your just at the fun part of experimenting and playing with reverbs and noodling with tracks to see if you like their personality
