Wideangle is king - for me, too!
Wonderful photographs - well processed with a lovely "old world" treatment, which is meant purely as a compliment.
I think the fourth photo seems to most "popular" perhaps because you have done a perfect job in composition, taking best advantage of the three-dimensional qualities of wideangle lenses with a strong foreground and leading lines through the photo to the background. With all four, we feel like we are "there" but with the fourth, especially, we are not only "there", but we can visually walk through the scene.
In the first, I feel a disconnect between the well and the distant building cut in half by the water. The second photo has the tree anchoring the right side, but no visual pathways leading throughout the photo. The third is a lovely, crisp silhouette, but without shadow detail there's no where to "go" but to the sun and along the rim of shadow.
The fourth is filled with visual pathways - the cobble road and various fence lines. I think I would have stepped to the left so that the intersection of the pathways leading to the bright area down the valley wasn't "behind" the tree. Otherwise, this is a wonderful image.
Oh how I miss Europe!
