I like the bittersweet chord progression, and the orchestration is pretty good. I especially like the solo cello and choir lines. The transitions and pacing of the song are excellent.
I think the main thing that's missing from this track is a strong, thick bass line. I'm not necessarily referring to bass frequencies - it seems you covered that. To achieve the desired warmth with this type of music, you need a strong underpinning that could just be a single bass note per bar played by multiple instruments.
You might want to reduce the high-mids in the master channel to get a more dreamlike and less in-your-face sound. Here's a picture of what I mean: https://imgur.com/a/qinVPr3
I first listened to this with my phone speakers, and the sound was very distorted. That can be fixed somewhat by using dynamic EQ on certain instruments such as violin and piano or using a plugin such as Gullfoss.
Nice work!
