Really cool piece, i like the idea(it reminds me a bit of Parasyte anime XD especially at 1:45 when the synth gets introduced)...piano sounds really cool with effects you put on it.
maybe the chords could be a bit more complex(but in cinematic music, simplicity is maybe the strongest feat)
The song clips at peak parts and(which feels more annoying)in calm parts...funnily enough that is an issue i had in my last song XD
I would recommend lowering the volume of the song or if youre running it through limiter, lower the gain.
if that would not solve the calm parts clipping then, maybe trying to automate volume of piano itself...or edit note velocity at the points it gets the loudest.
Theres alot of potencial, just getting that clipping and volume/loudness under control and oh boy. I kinda had the opposite when my songs were mostly too quiet so i had to care about clipping just, well not that far in the past XD
In the end this is a really cool cinematic piece i love it.
