Tough shots to work with. Not sure how to explain it, but I can't get my arms around what I would do if I were processing them. I'd probably hold the foreground a little cooler and warm the sky (as you've done in the later posts). I'd also consider looking into adding some clarity/depth by trying to bring out the trees deep in the fog. The clouds in the sky make the shot compelling, but somehow the color balance of the blue sky is slightly lack luster. This typically occurs when an entire photo is color adjusted - perhaps see if you can isolate the blue in the sky and touch down the luminosity to increase the depth of the blue?
Anyway, great images. Nothing really needed in the end.
