Windmills are OK - I like the BW conversion and actually like the way the vanishing point comes together - including the power lines. Maybe a crop a bit from the bottom, there's a bit much negative space in the road.
I really like the wall, I don't mind that the shadows are blocked up a bit, but might crop a bit from the top where it's significantly lighter that the rest of the frame.
I played with the clouds a bit, I think the problem is that the extreme highlight at the top of the frame draws the eye right out. I cropped off the top a bit, burned the top, dodged the centre, duplicated and multiplied the background layer and added a gradient mask to restore the foreground. I left the effect somewhat exaggerated, you could back off the opacity of the multiply a bit.
