Great, unusual shot. I like the contrast of the black and white dog against the clear blue sky and the lush color sof the cases of beer. The eyes of the dog get a little lost because of the angle of the light.
This is a cute photo. I like the negative space, the repetition of the Budweiser crates, and the position of the dog. That said, it's a bit of a stretch to think of this as a photo to illustrate OPPOSITES, although the title conveys the point. It's a good capture, and I gave you a six, but I wouldn't chose this picture to illustrate a story on OPPOSITES. 6
