Whispers of the Rose Queen

Design a very realistic book cover. It features a beautiful half-human, half-witch girl with hazel eyes, light brown hair, and freckled skin. She wears a black outfit and a dark, ornate crown. The background is dark, with white roses and a castle on a cliff. A shadowy figure lurks behind her. Beside her is a tall, handsome half-human, half-angel man with green eyes, wavy copper hair, sharp cheekbones, and a radiant smile. He wears a sleek black outfit that highlights his muscular build. The setting is atmospheric, magical, and mysterious.
