Okay, so I've included several book cover examples to help you get a sense for the style I'm looking for. Basically it should have my protagonist on the front, looking bad ass. Here are my descriptions:
The character: The main character is a girl around 16 years old. She has jet-black hair kept shoulder-length. She has one streak of red hair on one side (her left, our right). Kinda like Rogue from X-men, but red instead of white. She is Caucasian, but looks like she could be either really tan or mixed race. She is wearing leather armor and looks very attractive in a capable, warrior sort of way (no gratuitous skin showing, please). In her right hand is a spear. This could be held sort of behind her in a fancy stance of some kind. Her right hand is clenched in a fist and has a magic "brand" on it that is glowing bright white. I've attached an image of what this brand should look like. It should be placed on the back of her hand (with the little circle closest to her fingers, extending up to her wrist and up her arm slightly. Not too much. Her expression should be a mixture of apprehension and determination, like she's staring at an approaching enemy she is about to fight.
Environment: The area behind the main protagonist should represent a battle between light and dark. You should be able to faintly see the landscape (and I've attached an example), but it should look like there's light pouring in on one side, and darkness on the other. The colors and lighting should take precedence over the details of the landscape, though I still want that to be there. The lighting should also help the protagonist "pop" off the cover.
I will leave the lettering up to the artist, depending on what they feel appropriately complements the rest of the artwork. But this is YA High Fantasy, so keep that in mind when designing. I definitely want it to stand out.
The dimensions are for a 5x8" book cover. I've attached a CreateSpace template but keep in mind that the spine width depends on the page count, which is not final yet. Please add some wiggle room. I'd like the front 5x8 cover to be high resolution. At least 2820x4500px.
