Your horizon line in both shots is actually curved, which will be a function of the lens. This may be also what is giving the impression of the leaning lighthouse. If you have pp software that has a lens correction feature you should be able to sort it. If it was just the lighthouse then keystoning (it's called perspective correction in my s/w but may be different in others) would be your answer. I'm only looking on my laptop but the first has the makings of a really nice shot.
BTW is it 'Star Point' or 'Start Point'?
