I really liked this piece, I very much enjoyed the energy, it has some elements of Chopin in it. I would, however love to hear a bit more than straight arpeggiation in the left hand, or... whatever hand of the four was doing it, to create some more harmonic interest.
I really liked your melodies and your textures were very cool. But with a piece like this, with such straightforward harmonies, I feel like it needs a little bit more dissonance with some nonharmonic tones, nothing insane, just a few graces here and there would do it.
Definitely held my interest though. Good work!
