Billboard photography research

During my research for my billboard I need to look at landscape photography this is because of the type of billboard I am creating. I am creating a coastal billboard that relates to Cornwall, when typically looking at these type of photos you can see they're high-quality images and have been usually been focusing on the sea and cliffs of the coast. One photographer that is taking images that I want to do is Lee Searle, he specialises in landscape costal photography in Cornwall. Some of his work is below and you can clearly see he focuses on the sea and cliffs of the coast. I want to incorporate this for my billboard as it shows the rawness of the coast but I don't wish to include such a neon colour pallet so I am going to adapt that myself.
