Impressive, grasshopper.
I gotta say, I like this. The use of the ambient sound effects is nice, though I could say that it might be worth your time to allow more to gon musically as they play. Not so as to obscure them but just to add a little more flavor. Also, some ambient transition material might help improve the feel, I.E. a wind slowly picking up and diminishing just as the next section starts.
Great song, keep it up. I clicked on the first thing I saw and got gold, I'll be exploring more later on.
