hi, still very new to music production but ill try to give feedback as best as i can
main thing i can say is that the progression of the song is a bit bland and repetitive, i suggest trying to add more interesting chord progression changes along the way, or maybe change the instruments and beat pattern. i get that this is supposed to be more of a calmer track though so the transitions between parts dont have to be too intense, some slight changes usually are enough to spice up the track by a lot
might just be me but i also hear a bit of dissonance between the instruments, like sometimes the lead doesnt match the chords, like this one section at 1:32 in the start of the 2nd bar/measure(? dont really know the proper term of it) of the new section, which repeats itself for a while
i think the drums get in the way of the instruments and creates a bit of muddiness especially in the parts where theres an extra bass, i suggest eq'ing the lows out of the instruments or maybe sidechaining?
last thing, the song could probably have some sort of outro so that the conclusion is more satisfying and not just an abrupt stop.
i think thats pretty much it :) hope this is somewhat useful
