Very, very nice.
I like how you made the music merge into the background and drift back into the foreground every now and then. I feel the only improvement that could be made to this is that there are several points where more advanced rhythms could be used to great effect.
[The rhythms you already have are fantastic, don't get me wrong. I just sense room for improvement & development.]
I like the choice of instruments; The track is well balanced, no instrument is too loud or too quiet, everything sits well in the mix.
To me this is a 9.5/10 however there are no halves so here's a 10 instead :)
Well done.
