I particularly love #2. It really holds my attention, so much to look at.
Two thoughts, maybe dispensable. I'd crop off just a tad more from the bottom, the grassy knoll in the centre attracts my attention just a tiny bit too much and so I'd crop off just past the two small stones on the right of the foreground knoll to force attention back to the centre more.
Maybe use the warp mesh tool (not sure what it's called in PS) to straight up the lighthouse a little ? It may be naturally at that angle though so I could be talking rubbish !
