I like this picture by Henri Cartier-Bresson. This picture uses the simplicity of a black and white picture and is simple in general. The reflection of the kid in the water gives a really nice effect that attracts viewers to view this picture.
This is a photo by Matt Stuart. I am a huge fan of his work. His sense of humor and being in the moment at the perfect time makes the most entertaining photos. As you can see the poster in the background is silencing everyone for the napping lady.
