This is a VGM Challenge review.
I like the double bass (I think) rhythm. The upfront, sharp transient percussion sounds out of place in this ambient orchestral context; furthermore, it's relatively dry to a point of distraction. I like the other percussion a lot; it seems you used string instruments percussively. The song makes me imagine exploring a dungeon in a rpg that takes place in a medieval time. I'm not getting strong Northpeaks vibes, but I suppose this song would indeed work in a dungeon environment in such a game.
I like the eeriness of the flute lines. It helps establish an otherworldly, creepy vibe.
The song lacks a proper intro and outro, and it doesn't seem like it's meant to loop. I would like to hear more sections and development, but this is a good start.
