The job of any cover artist is to convey what your book is about – be it from a quick glance, a tiny image or your cover splashed on a billboard. It’s vital to convey the feel of the book, maybe even a character or two, but most importantly, play up to established expectations. Historical romances generally have sensual fonts and silken fabrics. The latest trend in paranormals is to have wicked body art on gorgeous male torsos. Notice all the hot females with weapons (swords or firearms) lately?
If your book have any of those elements, play them up to get the most exposure! We don’t want your book to look like everyone else – but at the same time, we want it to be identifiable by those readers who are looking for what you’re writing!
