Some nice images. Number 1 is my pick of the three. It has the potential to be a real cracker but for me I would have lightened the darker parts of the foreground slightly and also the (your?) shadow in the bottom left corner is a little bit distracting. Lovely lighting on the hillsides in the background though, and you got a great, moody looking sky.
I like the 2nd one also. Did you add that fog in with PP? The scene looks a little bit too bright for it. I think if the image had been darker then the fog would have added a bit of a mysterious feel to it
