I need a cover / standout graphic for an e-book about aromatherapy for the brain. I don't want it to be a graphic in a typical herbal or esoteric style, because that's not what the content will be. In the e-book, aromatherapy will be described in a scientific, biochemical, state-of-the-art, research-based way. I would like the cover style to match the style of the content, i.e. be modern.
Applications with examples of similar orders are welcome.
