I find this piece to be incredibly immersive. The imagery really closely matches the vibe of the song. The translation between the written idea and the music isn't perfect IMO in part due to the gap between the piece's length and the length of the description, but the imagery I get from this is still very clear.
I'd love to see an expanded description and plot that I can follow along with. It takes almost 9 minutes to listen to but takes me much less time to read the description.
I find this incredible nonetheless due to its immersion.
BTW I have a bonus suggestion you can consider playing around with if you want: find someone with a good, calm narration voice and have them read the description out loud as the song plays. Even if you don't end up using it in the final song it may help with pacing if you choose to add to the description.
I hope this helps. :)
