For this shot, I'd crop some of the bottom out to just under the fence. I am feeling like the fog is almost getting lost in the frame and that the cropping will help keep the focus on it. I like that the colors are subtle, but it feels like it needs something but I'm not sure what. Perhaps a bit of a contrast boost?
I agree - this is better. The saturation boost also brought out more color gradient in the sky, adding more visual interest to the top do the frame while still maintaining that delicate morning mood. Good edit.
