Good, but...
I like how the song is only played with a piano, and I like the piano itself, but there there are a few flaws you might want to fix.
While the song is mostly played correctly, I think I can hear a few wrong notes here and there. You might want to fix those.
Second, The piano sounds too auto matic. Like its a software instrument. try making notes extremely slightly off time and maybe add some more reverb.
Third, I like how the song was somewhat simple , but some parts can use a bit more complexity. Instead of switching back and forth between treble and bass, try combining the two.
Aside from some of those things I pointed out up there, the song is pretty smooth going overall and I really liked the classical sound you put onto this amazing score.
