This piece demonstrates a good sense of progression, and I like all the mellow and smooth instruments you made use of near the end.
Two main points of critique though. The melody is a little simplistic for my taste (though the supporting instruments do a lot to make up for this) and the song's perhaps a bit quieter than it should be. Perhaps a remaster to raise the volume a bit would help, so long as you don't go too far.
All and all, I think you did a good job here.
