Seeing the origional and hearing your thoughts perhaps changes the perspective of what your trying to achieve with the shot, and your certainly right; the crop grows on me more when I stand back and admire the image as one piece. I would have used a bit less sky, and perhaps lost the overall dramatic effect. It would be tough to gain that otherwise in the shot.
The people, while distant and tiny, still anchor the shot, and its good that after admiring the shot as a whole, you are still drawn to the detail of their presence, in perfect position within the crop, and ultimately along the trail on the ridge!
While working on the highlights, I'm drawn to loon. What time of year was this (obviously summer but was there still snow on loon's slopes?) I think perhaps those highlights are blown out a bit.
I don't want my ever so minute points to take away from an amazing shot, and I do love the color balance that you've achieved!
