I've created more pre-made cover art files and have them posted on my site. If you are interested, please drop me a note.
Information up on my site: http://sherimcgathy.com/sheri/book-cover-design/premade-covers/
You can also see samples at my Facebook page:

Most of the samples are for the front book cover/E-book cover but I can create for paperback, as well.
Here are a few new pre-made samples.
