It appears you have made a piano soundtrack, nice. However, I do have some improvement tips. Your part that starts after the intro is VERY off key, if we could fix that it would be very nice. Secondly, I recommend using more sustain in the notes to give it more vibe. Add reverb for bonus. And maybe don't just use the middle octave, it makes it bland. My recommendation would be to play around with sustaining the notes to at least double the amount (for notes which have wider gaps between other notes) and also to make expressive chords. And not to make it off key :) overall I give this a 4/5 because I think it has potential, just need to work a bit more on the flaws :)
