Like the piano...
The piano with the drums are nice, but the revving sound is distracting. It could use even more melody changes, and then it would be good. Right now the piano just stays in a little nest of notes, but if you branch it out to higher and lower notes, it would sound better.
As I'm righting this (I didn't think it was going to change at all xD) the...synth?...came in. Whatever it is, I would've liked it in earlier. Right now it comes in around 4 minutes, it would've been better coming in a 2, when I was getting sort of bored xD
Keep the focus on the piano, and change the melody around a little more, and you'll have it.
Please contact me if you would like to use this in a project. We can discuss the details.
