Incredible! The main motif here is extremely beautiful and catchy, I love it!
All the tracks are fantastic in their own way - the first one is so fun and such a bop, the second track is menacing and frantic (yet also a bop!), and the last track is so serene and beautiful (this type of solo piece that's based on a well established motif always has my weak in the knees). The entire ost went straight into my playlist!
I also really liked how you connected each track individually to the theme, that's really unique!
Extra shoutout to you, using a real recording of a piano, which is something I've been personally itching to do since the last jam I've been in.
This is great! Awesome submission!
