Very unique style you got there !
As a pianist I liked the solo piano approach, and you have some great ideas ! You really kept me surprised all along, and it does feel you're telling a story and create differents atmopheres in each part
There are some great dissonances, maybe sometimes a bit too much, I would have added more rests and "breathing" points, but overall I think it's great !
My favorite part is from 1:25 to 1:55, I really loved that intriguing motif and colors. It made me think of some FFX OST Theme (which I really love)
Good job !
