I have no idea what quartal harmony means, gonna have to look that one up. This is really unique, sounds like it could be heard in some chill place in an RPG.

Never heard songs from the "Tales of" series, assuming you're talking about Tales of Symphonia and others, but this sounds really weird and interesting! I'm curious on how you made it.

Oh yeah I remember watching that anime! I like this, I think you could've added a new section with a different chord progression to give some variation.

I have no idea what this is about, but it looks sick.
