Does a lot with a little! I really appreciate more scaled back arrangements (with only like max three things happening at a time). I think you’ve chosen the instruments and sounds very well and it’s nice that you give a lot of emphasis to those sort of “click-y” delays that really amp up the tension. The melody on the thumb piano/vibraphone sound is also quite nice and doesn’t overstay its welcome. Also nice that you add that string countermelody in the second half to bring in a bit more contrast. My only critique would be on some of the mixing decisions. I find the center of the mix slightly busy (sometimes with multiple percussive elements overlapping). And also thought the low strings were a tad bright and cutting into the melody’s frequencies a little. But honestly these are more nitpicky/personal preference.

Eerie, somewhat dramatic vibe. I got a feeling of threat and fear of the unknown from it, which I really enjoyed! Your choice of sounds/instruments also perfectly matched the theme! Nice work! ^^

I really like the instruments here, especially the main melody, the chords also give the song a mysterious feeling for exploring underwater!
