Create an ethereal autumn leaves deity with a focus on intricate details and epic beauty. Imagine them surrounded by a blazing, ethereal fire that casts dynamic, volumetric lighting across their features, akin to a high-quality 3D rendered masterpiece. The scene captures the essence of an oil painting on canvas, inspired by Greg Rutkowski's style, showcasing hyperdetailed elements and a rich, detailed background as befitting of a DnD character portrait. The character should embody a blend of traditional and fantastical elements, exuding a sense of majesty against a stunning autumnal backdrop, akin to those found on ArtStation character portraits.
