My new Rocks and Minerals Ebook

Lord willing I am going to create and sell an Ebook about Rocks and Minerals! I would also be happy if anyone can tell me how to make a title for an Ebook using Open Office. Since I didn't know how, I edited a picture of Rocks and wrote "Rocks and Minerals" on it. Here is the cover.

Sorry the title is a bit blurry, lol. It wasn't blurry while I was writing, it just saved it that way. Please don't let the title keep you from buying this Ebook.
