Not bad
Composition wise, I like it. It flows naturally. The piano sample(s) are pretty good, I wouldn't worry too much about because A. you can't do much about it, and B. they aren't very bad in the first place. The introduction was a little long, I would shorten a little... (not really an issue though) in addition, the song was a bit repetitive at parts. Other than that, it was great. (then again, I do enjoy Classical music, so I might be biased.) All in all, not a bad song.
