I enjoyed the layering of the first track into the second with the heartbeat thing you had going. Also thought the arpeggios and general vibe in track 2 fit your story really well. Track 3 could probably use a stronger bass layer it’s pretty piercing on the high end which makes it not the most pleasurable listening experience despiste the cool melody on top.
Sunless garden: I liked the rhythmic feel in this one. I’d say I tuned out a bit part way but it seems like you were going for a more ambient feel so that might be part of the deal.
Voices of the mist: similar comment to previous track
Enjoyable listen, I think if you work the mixing a bit more/ be more conscious about filling out the track it will sound even better! Definitely leans towards an ambient vibe for a lot of it, so if your goal is to grab/keep attention you may want to go in a slightly different direction, but if you want an atmosphere I’d say you did it!
