This picture follows the rule of "filling the frame," and I picked this particular one because I love the way the way the reddish-pink of the flower contrasts the stark green of the leaves. Had I not moved in close to the flower, the picture would not have the same popping effect that it does.
I chose this picture of my dad playing pool as my example of "leading lines." The cue stick leads the viewer's eye to the subject of the picture, my dad. I found this rule the hardest to photograph because most of my pictures either had to be set up or taken at odd angles.
The picture of my bed frame to the right represents the rule of "repetition." I was just sitting on my bed and realized how cool the interlocking circles would look in a picture taken at an angle but that still showed their obvious repetition.
