You've got a great-sounding piece here, but it needs work.
First, I think you need an intro. It's really up to you, but it seems like this starts very suddenly with the very best part of the song.
Second, you need to add more variation. The repetition gets quite boring pretty fast; it's just not good enough to repeat that long.
Third, I love the start, but the rest of the song kind of beats it down.
Thanks!
