A mystical sorceress, dark brown skin radiant in a dramatic black gothic ball gown, her raven hair and tattered dress billowing wildly as she summons the elements, hurling electrifying bolts of lightning, her face illuminated by crackling arcs of energy, set against a dark, moody backdrop of foreboding storm clouds, reminiscent of J Scott Campbell's dynamic inkwash style, infused with stylized watercolor textures and bold, contrasting colors, blending white, black, and electric blues, evoking the fantastical, detailed matte paintings of epic fantasy concept art, in the style of Wcol, with intricate, Unreal Engine 5-level details, perfect for an 8k resolution, Artstation-trending masterpiece, ideal as a themed phone wallpaper.
