Good work! And another where the source material is new to me… but I wanted to take the song at initial impression. I really like what I think is the ‘violin-ish from acoustic harmonics’ sound that you came up with - the bending back and forth between notes feels quite organic. The bits of percussive elements offset well against the warmer acoustic guitar which emphasises the unease you mention.
Overall, really enjoyed it and thanks for taking time for writing up a bit about the inspiration and how you wrote it. That’s what is especially valuable about these challenges. And interesting!
