feedback is cool
The pizzicatos seem to stick out through the mix. It doesn’t quite blend in with the rest thematically. I can say the same for the strings in legatos. Maybe try adjusting something that makes it a little more washed out like the piano. The piano is fine, it does have a nice hall reverb.
The “bass guitar” heard throughout the track is notably intruding the midrange. Personally would cut the EQ above 500-600 Hz range. Alternatively, opt for some more sub-styled bass guitar.
The drums are drowned out by the bass guitar. Doesn’t sound like the drums are in front of the bass guitar, resulting the mix being a bit muddy. Maybe it’s not exactly drowned, but I believe tuning(literally tuning the pitch) them a little is required. Maybe it’s because of the boring pattern it puts up? The kicks are fine as they sound like heartbeats.
The mix is highly dynamic observing the entire wave map:
It doesn’t quite hurt to slap a compressor on. The loudest instrument is the bass guitar, and I personally don’t like putting bass as a centric frequency in these kind of chilled genres. They especially don’t stretch out to mid-range, and often stay sub-bass. I provided some examples on Spotify:
