The book is 5.25" x 8" (front cover dimensions). The front graphic will be used for both a trade paperback (print) and a digital eBook. As a result, the graphic must be adaptable for both media. The front, back and spine must be included in the final design, but for the initial consideration, only the front is critical. The final graphic must be in a layered PNG format to enable me to modify the title, author's name, etc. A specific location must be left for the barcode; this is fixed and cannot be moved. The preferred color scheme is RGB, not CYMK.
The attached file is the winning design for my "Modern Family" book cover. Notice that the back is an open design that allows me to put in my author's picture, bar code, blurb, etc., without disrupting the design. The title for this book is quite busy; "Allure of the Incubus" is much more simple. As the design progresses, we can work to fine tune these elements.
Also, "Modern Family" is a highly graphical design; "Allure of the Incubus" should be softer, more realistic and, above all, romantic.
