in shot #1 i have seen these fences diving into the water and I always think it would make a great shot, especially on a calm day. I tried once and found the results very unsatisfactory from a a composition point of view as they a so strong a feature that they dominate yet on their own do very little for the viewer. #2 is a stream. #3 again, the posts end up being the composition in itself but they aren't that interesting (plus there's quite a bit of haloing aroufn the posts).
I am thinking that this is a bit negative but as Kevin said, they don't hold my interest. sorry:shrug:
