I like the mix between tonal and Atonal. Also there is a quite nice melody in it aswell. The piano seems to be doing all the atonal stuff. It is quite a funny piece to listen to, nice, because the atonalness, there isn't much to improve on. Some of the chords that are very dissonant, I liked. Also, there could be more minor like morivou said, and more augmented chords too, I like them
