My review, your song.

Mix your slayer a ton. Its a pretty awful imitation of guitar sounds and requires heavy EQ, some distortion, reverb, and chords. Keep in mind guitar songs are often built upon power chords and whatnot, not just individual strumming.

To be lazy 8ths will help fill out the guitar sound.

Drums here are pretty good, they are clearly FL presets though. Limmit and compress your drums.

Song progression is a bit lazy, just kind of plays and plays a constant bridge. A chorus didn't sound evident, but to be totally honest I zoned out while listening to this the 3 times I played it over.

The song writing needs more contrast, and you need more experience with mixing. (Or just a better guitar plugin.)
