So, here is my first Briefbox Submission and here is a little in sight into how/where my idea developed.
I wanted to keep the book cover fun and decided for the typography to use pastry for the book cover title. To ensure the typography stood out and made a powerful impact I kept the background in a plain stone colour. On the back of the book cover I used a strong a striking image but kept this quite simplistic. (I used Lorum Epsum for the back cover text just for imagery terms to see how it all looked.)
Look forward to hearing feedback on this brief.
