Oh wow, this is really neat! The melodies, chords and the progression are all interesting. I love how you put a few grace notes here and there too. The reverb works well with this particular sample and style.

The breakdown at 1:51 is an interesting touch! I like the jazzy style here too. Tempowise, you did a faily good job of humanizing the piece here, and all the way to the end! The ending leaves us with an interesting atmosphere too :O!!

This is a short review, but that means there wasn't much for me to criticise ;)
Ofc, a better piano sample would make this even better, but you have what you have. If you ever feel like you've made a really good piano piece (or just otherwise want a better sound), feel free to send the MIDI my way, and I'll export your song with a better piano VST, no questions asked, and no credits taken!

Octatonic scale! Fancy. It sounds inherently a little melancholic, especially with the dissonant notes at around :22 and other places. It has a smooth sense of continuity, yet also seems very succinct and well-structured. I also like the little turns and ornaments (e.x.: 1:17). The mood at 1:39 got much more blissful and reserved, and I like how you kept the sound nice and spacious going into the breakdown section at 1:58. You use modulations a lot. In my opinion, 2:25 didn't do much to add a sense of direction to the piece. Sometimes varying the melody is a more meaningful way of creating a final climax rather than simply modulating it. Either way, cool piece. The ending didn't seem as fleshed out as it could've been, but this piece has a great mood about it. Nice work, BO. ;)
