Hilariously enough, the piece you based your song on was one of my original thoughts to use for my AIM 2022 song! XD Besides that, yeah this crushes hard...actually was quite unexpected given the source used for its inspiration, but my guess is it kinda invoked that end scene from the game Faith (if you played it) where the protagonist priest is driving away from the house...some real horror / spooky-feel. I think the only drawback (for me anyways) was just that your song is so dissonant from (at least) my interpretation of the artwork, but we all have our own interpretation of artworks, and it fits your description of how you viewed it. :)
Good luck with AIM 2022! Have a good one. :D
