Could be improved a bit
Make sure your guitar is in tune, a few of those power chords "wobbled", unless this was intentional. A more diverse drum loop could help the song, but it sounds like youre more of a guitar guy. Maybe find a way to use less distortion with the same amount of power? It interferes with the overall piece a bit. The tapping/hammers are cool sounding, though could be cleaned up a bit. Spend a bit more time on the composition process, if you think youre done in five minutes, take five more and change something, then change something else. Same with the recording process, if something doesnt match your expectations for recording, punch in and fix it. With some refining, you have potential.
Yours,
