Esprit d’arbre féminin couronné de fleurs et de papillons

32k panoramic masterpiece, multi-exposure digital art. A majestic Mother Nature tree spirit with a serene female face emerging from ancient, gnarled bark. Delicate branch patterns vein her skin. Her hair is a lush canopy of autumn flowers and vibrant greenery. Swarms of hyper-realistic, iridescent butterflies in orange, blue, and gold flutter around her. Background: a breathtaking valley with a crystal-clear waterfall flowing into a river, misty snow-capped mountains, and soft sunbeams. Unreal Engine 5 style, volumetric lighting, cinematic composition, surrealism, ethereal atmosphere, highly detailed textures.
