Personally, I’d distort the image to put the lighthouse vertical, and I’d give it a tiny little rotation, and the horizon’s not quite straight (only by a tiny fraction though!)
While I like the shot in general, it just doesn’t quite make me go wow, and I’m not sure why. I think possibly just the rock doesn’t hold enough interest for me, so that the lighthouse is the sole focal point without much left to look at, if that makes sense… Maybe a little earlier / later in the day would have given a little more shadow along the rocks, adding to the impact? Just a few thoughts…
