What I would have done:
- Replace the digital piano with a live piano performance - makes it all much more warm and engaging imo.
- Add something more than only the stabbing piano chords, play some dark notes between those stabbing chords to keep a steady line of depth in the piano melody.
- Slow down the tempo a little bit, like 4-6 BPM.
- Add a very soft and very dull and quiet pad, just to give a slight spacial lift, nothing dramatic, just letting it be far away in the background doing its job. It might not work, but then at least you tried it.
- Some kind of bass sound. Even if you don't want that much bass, it's always good to have some kind of fundamental element that pulls the beat forward.
- Add more transitions.
- Change the rythm of the pluck from the static 8-notes to <this kind of rythm that I don't know the name of> but it's like this

- Let the pluck fade in and open up earlier so it's more expected, right now it comes out of nowhere.
- Add some slight spacial FX to the drums.
Again, this is just what I would have done, but hope it helps.
