Excellent work, these are really nice. How recently were you there, I'm surprised how much snow is still on the mountains if these are recent.
Some C&C....
#1 - I really like the reflection, and you've got fantastic light on the trees and mountains. The placement of the 'centerline' of the reflectin bugs me a bit though; I might try cropping a bit from the bottom and left to get it closer to the center of the image. If you're going to have some empty space, I'd rather see it in the sky than the water. The empty area at the bottom of the frame makes the composition feel a little unbalanced to me. I can't help but look at this image and think you should have shot it as a pano, but then I'm a pano freak...
#2 - I like the way your composition and viewing angle emphasize the steepness of the canyon, and I like the placement of the waterfall in the frame. The B/W conversion is also good.
#3 - Great environmental portait. The trees ligne up nicely along the frame edges for a pleasing composition, and I like that you caught the bear mid-step to imply some movement. Perfect lighting for this kind of shot. I also like the color contrast of this image, the way the carmel color of the bear stands out what is otherwise a mostly monochromatic image.
#4 - Love the atmosphere, and the composition works really well.
#5 - Excellent composition, this scene is well-suited to the pano format. The uneven sky is unfortunate, though I would think you can even it out some in post-processing (Viveza works pretty well for this sort of situation). The upper portion of the barn looks unnaturally darkened; I do realize the barn is some darker towards the top, but that seems to be exaggerated hear (grad filter?).
#6 - What a beautiful shot. The flowers make a fabulous foreground, the mounts are sitting in just the right position in the frame. This is my favorite shot. There's a bit of a sign of grad-filter or exposure blending on the left side behind the flowers, but a little burning could easily fix that, and it's really a small thing.
#8 - Love the atmosphere here, and it's nicely composed.
#9/10 - This shot doesn't work for me in color, the lighting is just too hard. It _almost_ works in monochrome; the high contrast works for the foreground flowers but I wish the mountains weren't in shadow.
