Generally good, but a few points:

Pan flautists need to breath too, you know.. I think it would feel a bit more natural to have some rests in the pan flute, i.e. take a few beats off the sustained notes at the end of phrases. Also, there is rather a lot of reverb on the pan flue.
The melody itself could use proper sections of variation rather then simply repeating the same melody again and again but with different countermelodies underneath, to show that there is in journey within the music as well.
I like the percussion.
