Ahhh this is my kind of chord-lines. It sounds great! It has that classic Japanese VGM jazz sound to it. And I LOVE the mastering. I know its not for everyone, but personally I like the low mid and bass to be center stage like in this mix. As for constructive criticism, if there was anything to point out its the synth at 01:55 and to the end, it cool that its wonky but it ends up fighting for space a bit. Might just be personal preference :) Great piece!
