I feel that I struggle to find ways to incorporate harmony when I work with just 2a03 since my crutch is the VRC6's pulses to make everything better and I usually like those flowing, chained suspensions. I was too scared to use arp (0XX) chords too in a lot of the places and maybe that was a bit of a solution. I also like to use that silly speed echo arp thing way too much in the background to add depth - another crutch.
In terms of "serious original" work I've done for the 2a03, this may be the first one. I'll definitely be much more mindful of that in the future. Thanks for actually constructive and awesome feedback :) I really appreciate it.
