Well since you're so open to opinions then I will; Firstly more harmonic progression, there are a few to many drone notes that stay the same for over 10bars at a time. I know it's midi, but even still it's good practice to work on shaping the piece even when it's a simple loop. For example try separating the beat track into separate tracks and think how you want to lead from there. Anyways it's always great to see artists posting their works as openly as you, good luck!
