Not being a pro in any way, I think you must be it. It sounds very, very well and I like it a lot. Strange that nobody has made any comments. If you want any response you must be active yourself commenting other people, I think.
The use of the wind is very good and also the offbeat guitar give the composition the right atmosphere.
Personally, I would give up the strings and replace an organ or synth.
More percussions, less drum breaks and 6min are definitely too long.
