dj-Smilee said it right...
...and I agree. Great work!
I'd just like to add one thing: I don't think the piano sounds bad at all. I think what's missing could be some orchestral strings i the background from 1:08 to 1:36. It would hold the piano nicely and give it greater purpose IMHO, but that's just a subjective opinion.
Anyway 5/5 from me. Keep it up (and wrap it up too...)
