Thanks to everybody for all the feedback, it's much appreciated.
I may need to rethink the shadow tones on the Half Dome shot. On my calibrated display at home, there is still detail in the shadows; but on my work computer they're too dark, and several others have made that same comment. Some of it may come down to display differences, but I think I can probably lighten the darkest shadows a bit without losing the overall tone of the photograph. For me that middle layer of shadow with the sun-lit foreground and Half Dome in the distance is what makes the shot. I only wish I'd had a better sky.
I'm glad to read that some others like the juniper tree shot, as I thought that was a really neat tree but wasn't sure if it rose to the level of a good photograph. I originally planned on the tree image being B/W when I shot it, since I tend to prefer B/W for subjects like that. I did try a B/W conversion, and I like it OK. But the trunk stands out much more in the color version, and I think it makes the tree a stronger subject. Here's the B/W version, I'm curious what others might think.
