The thing that first attracted me to this scene was the neon sign, slightly crooked, within the black and white frame of the window. But then the attendent, who had been out of my view on the other end of the dock, walked into my viewfinder, his shift almost over, and made a phone call. I thought his dark skin and white clothing complemented the non-color scheme of the rental shed in the background.
I held down the shutter button to shoot a lot of pictures with him sitting right there, but in this one, his body English and facial expression was the best of the lot.
Back at home on the computer, I noticed that the red life vests could make a nice design element, a triangle right into the left lower edge of the frame.
But only if I cropped the image to "OAT RENTALS."
