Cool, it's in D minor scale right? Starting chords are D minor - C - Bb, I think. I like the latter part more when you drone on the D chord and make a solid groove. Overall sounds post rocky, melancholic with a prog rock / punk ballad vibes.
I haven't played guitar much, though I have over a decade of experience playing the piano and know some music theory. I'm interested in composing my own music, but that's a plan for the future.
