If you could note how incredibly rough they are, especially the collage piece with the baby, locket and quotes from your book (too busy), and your name (illegible...). Please stress it was a concept piece and not a final. Photoshop has a sneaky way of looking too finished for conceptual work.
- Who is my most likely audience of buyers? Of readers?
- What are the successful "comparison titles" for this book, which we might want to subtly remind that likely audience of? (I admit this question is how book cover trends get started.)
- What emotions are evoked in or by the book? In novels: What are the most high-drama scenes or resonant images that might make a great cover?
- Which of those emotions would I most like to convey to my likely audience? Which one would have the most appeal to them?
- How can I build an image or design that will put forward that feeling?
- How much of the appeal can be carried by the title, and how much has to be taken up by the visuals? How will the two play together?
- Where will this primarily be sold? (If online, it's important to think about how the image will look scaled down to an inch onscreen.)
