After all you can't break the rules of photography composition unless you know them. I dug up a video on youtube that gives you a few simple rules of composition that will make you a better photographer.
Here are the rules straight from the video (the video's pasted below).
1. Rule of thirds: Divide your frame into 9 equal parts, then place the subject of interest on either the left or right column or top or bottom row.
2. Avoiding the center can add more interest to a photograph.
3. Lines are everywhere, using them to lead to your subject can enhance your photo.
4. Cutting down the middle between two subjects, you'll have an emphasis on each of two sides.
5. Try asymmetrical balance where one side of the image is balanced with the other.
6. A simple photo is more pleasing than a heavily cluttered one.
