This very good! You should be proud of yourself, this is a masterpiece. But don't let you push you down by thinking you can't be better, use this to say that you can be better. Literally everything is perfect in this track besides one small thing. I wish it had more than the rotating chords you had in the piece. I "b" section would be nice, but isn't 100% needed. Very good song overall. You have picked up on one thing I think every music artist needs to know which is having a "room" sound to your music. It is hard to explain it, but you certainly have it here. Keep up the good work!
