Thanks for your comments Chris - I am relatively happy about the right side as Mousehole is a very "cluttered" town, which is part of its charm, as is the crowded harbour full of boats.
Slight crop from the sky and left side.
There is a small cluster of boats on the left edge which is causing most of the problem. May need a bit of clone as well. This will still leave at least half of the distant rock.
But, the current image does look a lot better when viewed at full screen size. A large print is required for best advantage.
I hope you don't mind, I had a quick play. Please feel free to delete.
I lowered the exposure, removed a couple of boats on the left, removed some of the cars off the quay and removed the manhole cover that was on the path, right of image. I also think with a bit more time, the water where the removed boats had been moored could have been made a bit more natural.
