I hate to be a downer. I really wanted to give this an extra point or two, but could not. The mixing is great, the instrument choice good, the feel very calming.
But, the chords are so overused. I have literally heard this countless times. Not only that, but they never really change. It's the same thing over and over, although you masked it REALLY well and kept my interest throughout the song, which takes skill. I'll definitely check out any other work you've done, but I honestly cannot give this more than a 7. Either way, I hope you keep making music :)
