Nice work! The flow of the song is very nice. Something I recommend is adding some more elements to keep the listener interested. For example, in the bit with the piano chord stabs (1:30), add some synths like a saw pad to go along with it for more dynamics. Also for the piano, changing the velocity for each chord to give it a more realistic sound and adding reverb to widen the sound. Overall, adding more sounds will build on the dynamics of the song and keep listeners engaged. Good work! Keep at it!
