Open to concept. Can show hero/heroine up to 1/4 profile, and/or images from the book (lake cabin, classic guitar, tour bus, dog, etc.), but it must be unique and memorable. Photography style OK, but prefer portrait-quality art, or serious illustration style (not cartoonish). Will provide sample images and in-depth descriptions of characters. Need high-quality image suitable for print book via CreateSpace, as well as high-resolution web graphic.
