The gated pads in the beginning are damn cool. They play rhythmically random chords but on the melodic aspect they're fine. There's that dry weak gritty bass in the background, I can't really figure out what's its purpose. The chords are pretty harshy and. The square lead is pretty loud, it scared me XD.
The structure is pretty progressive, but why not turn this into a full song? That could be interesting. Greetings,
