I guess one problem is the snare at 00:22 etc. It's slightly off-timbre and off-pitch if that makes sense.
I really like the sound design you used here and how the piano chords are so low. The fills also fit right in with the song.
At 2:11 the supersaw chords are a little low and interfere with the kick and bass. Maybe that what you were going for, not sure.
Anyhow, nice job.
