Opening is a little too open maybe though. Might want something else in there somehow so it doesn't feel so blank. Maybe make some sort of obvious change in the mood of that piano as well, as it just feels like it's doing the same thing the entire time.
Good work though.
Thanks a lot for your review, I'll make a few changes to it!
Please contact me if you would like to use this in a project. We can discuss the details.
