I like the piano's sound design, the chords are very nice and thee general playing is very nice. I agree with House that it's not very connected to the theme, thought it was a hard theme lol! Though I do have a pet peeve that the sound is overall pretty muddy, one way you could change that is by making a separate channel for the delay/reverb and EQing just the delay/reverb so you can keep the tone of the piano without the delay/reverb getting too muddy sounding. Overall, quite good and wish there was more!
