For my man-made object/structure, I chose this shelf. The order/tidyness of the picture was very pleasing to me, so I simply tried to capture this by taking a front-facing shot. It took me a lot of tries to get it as straight as possible, but enlarged on the computer, I see that it is still a little crooked. . The variety of shapes and textures and the clear divide between the top and bottom (light shelf, light-colored objects vs. dark shelf/dark objects + shadows) were all things I considered in the composition of this photo.
