I like it!
Some things you could consider adding:
>a bassline: It could just be a low frequency sine wave following the chords, or something more intricate.
>a synth lead: I think that messing around with the LB302 synth might yield some cool sounds.
>percussion fills: Adding things like short little buzz rolls on the snare, or just appropriate sound effects would fit this piece nicely.
Lastly, it might benefit you to look into sidechain compression. Not necessarily for audio quality purposes, but it can be a neat effect and suits the style of this song very well.
Here is a tutorial by Cubician that is very brief but helpful.
I look forward to hearing the continuation of this piece!
