I find the organ synth (the one playing the chords) a bit too loud in the mix especially since it’s present through the song. I like the swapping of the melody between the vibraphone and the brassy synth, but I think the vibraphone gets a little covered up by the chords. The chord progression itself I found quite nice and liked that you spiced it up quite a bit with chords outside of the key (I think?). Definitely fits the jazz vibe and gives the song a lot of movement and also allows the melodies to go in more interesting directions.
