While all four are very appealing photos, my jaw dropped further open the further down I went, and while I liked 1 and liked the rush of the stream in 2 even a bit more, I really thought "hey", when I came to three because of the "diagonal streaking" of the frame by the aspens as they are sitting on those slopes ... and then came four and my jaw fully dropped.
So yes, odd one out who I might be here: I like the streaky character of 4 best of all. The yellow of the aspens really stands out so much against the rocky surface of their surroundings.
