Kachtcheï chevauchant un cheval démoniaque en flammes dans un château en ruines la nuit

Hyper-realistic oil painting on canvas, ultra-detailed, extreme low-key lighting, almost total darkness, dramatic chiaroscuro, deep shadows, rich oil texture, visible brushstrokes, canvas grain. Black and white image — except the horse, which is fiery red and blazing with flames. The rest of the image is monochrome, grayscale, no other color. Scene: In a dark, ruined ancient Russian castle courtyard at night, Koschei the Immortal rides a demonic horse. Koschei is tall, creepy, with a dry, stern face, skin white as snow, and a long beard. He wears a plain steel helmet with frightening symbols etched into the metal — ancient runes, distorted faces, and skeletal markings carved deep into the steel. He wears an expensive black outfit with detailed embroidery, and holds a sword in his hand. He rides the horse with a commanding, terrible posture. The horse: A demonic stallion, its body fiery red, blazing with flames. Its mane and tail are fire, its hooves burn, its eyes glow like embers. Flames erupt from its nostrils and mouth. It is a creature of pure fire and nightmare. The horse is the only colored element in the image — vivid, burning red against a black and white world. Lighting: The only light comes from the horse's fiery body and mane, casting a red glow on Koschei's face, his steel helmet, and his armor. But the image remains black and white — only the horse is red. Everything else — Koschei, the castle, the ground, the shadows — is rendered in shades of black, white, and gray. Deep shadows fall across the scene. Mist rises from the ground. Embers float in the air. Mood: Epic, mystical, tense, and terrifying — immortality riding death. Style: Painting style influenced by Andrey Yesinov (hyper-realism, sculptural precision, brutal detail) and Ivan Bilibin (Russian folklore illustration, decorative precision), with a hint of Mikhail Vrubel (demonic, mystical atmosphere). Negative: extra limbs, missing limbs, deformed limbs, fused limbs, smooth body, cartoon, 3D, plastic, anime, color, bright, sunny, daylight, evenly lit, modern elements, crown of bones, bone crown, skulls, bikini, clothing on horse.
