Thanks very much for your feedback!
Indeed I get a lot of inspiration from japanese games (lately a lot from Final Fantasy XI ost), specially when it comes to chords! But my approach to chords in this piece can be boiled down to borrowing from modes close to the key like phrygian with the iib chord and my favorite viib chord. I can talk a lot more about chords and harmonic progressions so feel free to reach me out!
Now quality I gotta stop being lazy and focus more into it, because I try to make my own instruments with synths available in the tool that I use and get lost trying to make them sound good. Also I don't know how to do mix and mastering so I think it's time for me to study!
