Sounds like runescape music.
I think it's great that you decided to make your own song, but the quality needs to be cleaned up (lots of static). Also try varrying the instruments a bit more- I only heard a synth, piano, flute, and drums- or increasing the complexity of the individual melodies to make the song more interesting. As previously mentioned, the ending could be smoother as well.
Good luck with your book!
