I listened to your music 3 times to understand why it was both magnetic and disturbing.
I finally understood! The melody is major pentatonic in F# and your bass follows a major pentatonic scale in Bb (basically, there's a 2-tone shift). I don't know if you did it on purpose, but it's great! So technically, you miss the challenge a little bit, but in terms of atmosphere, it's really interesting.
I really like the creepy effect at 52".
