I think there is an illusion of the tower leaning in the shot, caused by its more than averagely conical shape and the sunlight/shadow transition and how the brightness of the shadowy RHS closely matches that of the sky behind.
I believe there might also be a contribution of camera tilt (up) as well, but the -11 correction is too much; it causes bits of the house to lean the other way, I'd try -5.

Jeff and Dave, -11 correction doesn't seem too much to me , but it is personal preference and it can always be adjusted to one's taste . I just wanted to offer a solution for the tilted lighthouse issue
Very gorgeous shot!
