I took this shot while on a tour of Iceland. This particular shot was taken early afternoon but I wanted to transform it into a night time image. So, I adjusted the exposures and did add the moon and its reflection as a composite. Don't know if you accept photos manipulated like this but I sometimes feel a photo needs more to add emotion. I took this with a Sony A7rii, 16-35 lens at 27mm, ISO 50, f20,1/25 sec.
To me the moon doesn't add much. I think if you had moved to the left and back somewhat you might have gotten more of the sweep of the curving shoreline in the shot and that also would have set off that amazing huge rock in the water so it was more against the sky than against the cliffs behind it. I do think your choice of monochrome for this scene is a good one.
