I don't think you needed clouds. That light is lovely. Great lighting and use of shadows, great colour in the sky finished off nicely by the background hills. The only thing I don't like is that you were there and I wasn't. Seriously, nice one
That's just super and clouds would probably not add anything. I would crop away some of the smaller foreground rocks as they distract my eye from the larger sunlit rocks and lighthouse, but I can see why some would keep them in as they do catch the light nicely.
Thanks very much for the comments everyone. It was a really nice day - plenty of people on the beach (its a really nice walk from the car park to the lighthouse along a massive beach), some even swimming in the sea...in February !! Thanks again
No criticism of the shot, although I'd probably lift the shadow details a little, but nearly every view of this scene places the lighthouse exactly on the horizon line.
I know it's down to viewpoint, and maybe there are no alternatives, but if I were taking it, I'd try to find either a higher or lower viewpoint to change the perspective a little.
Looks like I'm going to have to make the trip sometime...
