I have five mock-ups for the cover of the third installment of the Mageri series. There are a couple of good potential design concepts and models, as I'm still going through potential model images. The real world begins in July when the betas will have the book; then I'll be able to devote the entire time to designing the cover, writing the blurb, and narrowing down the title.
It's always a good idea to begin things early so you can start visualizing the big pictures, and this is helping me tremendously with getting things kicked off. I'm really excited, even though cover design is a very daunting task. It's not just about visually interpreting the book or characters, but selecting a cover that flows with the series and is "clickable". Meaning: If you were scrolling down the Amazon list of books, would you look at it twice?
