There are things I could nitpick about this one; the lower hand drums being so heavily reverbed is one, the jarring shift from high reverb to low reverb is another, but I'm not going to do that here. Probably the only thing I'd suggest is about the same reverb on the flutes and other winds when the rest of the music dips out, but other than that:
I think this music needs a jarring shift. A lot of music of the prairies that we know and love comes from idealised western films, which of course don't paint an accurate picture of what happened here -- many of the settlers fled persecution in their own lands, only to persecute others. The strings(?) have chords that sound like fraying nerves, which is precisely what happened here.
If anything, if I try to picture a scene to this music, it'd be that of the mistrust (and perhaps distrust) that comes about when the natives and the settlers met on the prairie, with air distorting in front of one's eyes due to intense heat if you go further south -- that even if either side says they mean no harm, both sides are extremely apprehensive of each other and they know that one side is basically going to proverbially skewer the other in the rear. I can see it now: I can see faces twitching in disgust, just as the natives and settlers meet.
