Portrait en très gros plan d’une ancienne entité démoniaque

Extreme close-up cinematic portrait of a colossal ancient demonic entity's face and upper torso. Dark obsidian-like cracked skin with glowing crimson-gold light seeping through the cracks like inner fire, horned helmet-like head structure. Calm serene expression with glowing solid golden eyes, no pupils, unsettling stillness. Fire and energy swirling around the head and shoulders, glowing cursed symbols visible in the blurred background. Dramatic close lighting emphasizing skin texture and cracks, shallow depth of field, semi-realistic cinematic concept art style, hyper detailed, movie poster quality, 4k, intense atmosphere.
