Not very much a decisive moment shot in my view, but I love the horizontal layers of the sky, water and sand. Also, the relatively dark sky and bright light on the (vertical) people really makes them pop! IOW great composition and lighting! --Olaf
I like the definition between sand and sea, then sea and sky. But obviosuly the people make the photo too. I just think they're having a nice stroll. - Jono
To me, the picture is less about the dog looking for a game and more about the distance - both physical and emotional - that appears between the couple. They're wearing similar shirts which indicates togetherness, but there's nothing else that indicates a bond. Body language is strong here.
I think a change of title would actually help this image, though I'm struggling to think what would be suitable. Phil
