the chords made the hair on my neck stand up you're right as trancy as dicks.
I want to suggest adding more texture to it but I know that would ruin what you were going for, it's just after a minute and a half with little backing that riff starts to jar a little, perhaps if you do something like this again a little oscillation in pitch to match the chords at 1 or 2 points. but again that could ruin the atmosphere
