From a recent visit to Bridlington. Exposed for the sun to give a silhouette but a lot of glare and work with both burning and dodge tool that I'm not sure of. Two main choices, I think. Include the sun, or leave it out. If you place an edge on your screen to remove the top part - is that a rather better image?
