As a frequent visitor to Austria, I think all of these are lovely.
Some comments:
They all have a slightly other-worldly look, which I think comes from the processing.
§1, the green of the grass seems slightly unnatural.
§2, the pool of light by the shore, was this how it appeared at the time or was there some post processing help? I am trying and failing to work out where the sun is.
§3, the slow shutter speed has created a fairy tale impression. Not at all natural, but very beautiful.
