All the tools have been gathered, now it's time to sculpt the statue!
Mixing is alright, but could use some work as some of the instruments could use a re-EQ to make them stand out. Some things like the brass could have used less verb, the saw tooth buzz could use a re-EQ and some more variation on effects throughout. Don't be afraid to take it out of the song too, or switching up the sound while keeping the same instrumentation/midi. I love your use of Japanese stringed instruments! Keep it up
