To make a polite suggestion, to attract more readers to your books, maybe use PicMonkey, or FontCandy, or even PicCollage to make your covers have more detail and other stuff. I'd add a copyright just in case as well. I'm only thirteen, and I started when I was eleven. It takes a few years to attract an audience, but once you do, you're all set. :)
