The first is quite nice. On the other two, the sky is a bit overdone for my taste. The third has an interesting foreground, and might actually be better with only a sliver of sky, just enough to include the mountain, and also cropped a bit on the left.
You'll get more comments if you post in General Gallery. I didn't see these until just now because I usually check General first, then b&w, then this one, but only if I have time.
