Not bad. I have to say, I think that it's got a good sound, but the piano would be really good if it were somehow distorted, either with a filter, some sort of reverb/delay, and quieted just a little bit. It kind of sticks out as the most prominent sound in the song, and by the end of it, its own repetition makes the song feel more repetitious than it actually is. Know what I mean?
I'm curious as to what you use to make your tunes though. I like sound of the drums for sure.
