Well this a very nice. I recommend adding a drum pattern as well as developing the melody a bit further. I also recommend adding some passing notes in the form of either perfect 4ths or 5ths. It doesn't have to be perfect 4ths or 5th though. It can just be single notes as well. It sounds like the chord progression goes Bbm7 - A - F# - A. So to develop it further you can try Bbm7 - BbD# - A - F# - BbD# - A. But I think you should try also switching up the chords in the chord progression as well. Or maybe even extending the chords or adding inversions like Bbm7add13 - BbD# - A/E - F#maj7 - BbD# - A.The just gets a bit too repetitive due to the chord progression. I think the kick is too loud. I think you try to "tuck it" under the song a bit or have it blend in more. Probably with some reverb maybe or/and if you're on FLM, a filter. Also I think you could add more in general like the drum pattern, a nice sax, maybe a bass line. Maybe a bass that plays the notes (not chords) Bb - F - Bb - F - A - C# - A - C# - F# - Bb - F# - Bb - A - C# - A - C#. It would probably be like quarter note then an eighth or half note then a quarter idrk.

Overall I think you can expand on some things but I do like the chord progression. I just feel it can be a bit more interesting as things progress. Pretty nice and chill.
