A high-quality anime illustration captures a majestic white great serpent in a fantastical and solemn atmosphere, depicted in a dynamic low-angle medium shot with its massive head reared up imposingly toward the viewer, mouth agape revealing sharp fangs and a long forked tongue extended outward. The serpent's scales glisten with intricate iridescent textures, smooth and porcelain-white with subtle pearlescent highlights, coiling body partially visible in the foreground twisting powerfully. Its piercing red eyes with slit pupils glow intensely, conveying a cool and intimidating gaze without horns. Ethereal mist swirls around its form, ancient stone ruins and glowing runes faintly visible in the blurred background. Soft volumetric god rays filter through, cool blue-purple color palette with crimson eye accents, depth of field emphasizing the head, intricate scale patterns, glossy saliva strands on tongue, serene yet ominous mood.
