I see issues with all of them, some of which have been pointed out. I'd suggest for future shooting to try to get separation of the elements in the photo. That is, in your second set, moving a little bit to get the windmill tower separated from the tree instead of being in front of it would have worked better. Some scenes just don't work out either - you position yourself to get certain things in place and you introduce some other unwanted element, try to get that out and some other thing pops into the frame. Maybe that's this scene.
I looked again, that tree is so close to the tower it probably wasn't possible to position yourself to separate it from the tower, but still, something to be aware of. (I mention it because I do this all the time, only see it later, on the computer)
