Here's an old cover of mine. It's the level 9 theme "Klepsydra" from Falcom's Xanadu Scenario II, what appeared to be an upgrade package for the original Xanadu game for various old Japanese 8-bit computers.
I was trying out using arpeggios to have the bass also act as percussion with the noise channel (This was before I learned how to use effects properly.)
I like the unorthodox use of a square wave for the base. Definitely suits the rest of the song. Unfortunately, I don't hear much of the fancy percussion mixing that you were going for... Still very good though.
