If you copy a melody or pad to a second note track a cool thing to try is to move one like 1/128 of a bar later and then lower the velosity of the notes so it mixes just right in with the original melody or pad :~)
I like the pad and the lead melody that's a nice touch. Maybe give the bass more distortion by shaping it with the waveshaper so it's dirty but also soft at the same time. The crusher bits is distracting to me but it sounds interesting, maybe taking out some of the ear piercingness would tame it more.

using iPhone13 speakers. It sounded fine, though I can see how the “marimba-like” synth notes could push the limits of some headphones.
