Portencross Sunset with Small Cloud

Technical: canon 5D3, 17-40 lens at 20mm, ISO100, 2″@f/16. Lee filters on the sky.

Conditions: slight breeze at sunset with a gentle swell on the water.

I can’t make up my mind about the balance of this image. There is a diagonal that goes up to the small cloud and seems to balance with the small rock lower left. It’s bottom heavy. Perhaps a square aspect ratio but then those nice lines in the rock are lost.
