demon skull horror 3d model

A nightmarish, grotesque cosmic horror boss. The neck ends in a jagged, smoking black void with no head. A massive, screaming demon skull is fused deep into the exposed ribcage and chest cavity, glowing with piercing crimson abyssal eyes. Distorted, elongated limbs with sharp claws, draped in tattered dark spectral rags that float in zero gravity. Ominous atmosphere, heavy shadows, evil presence. Stylized flat paint texture, dark fantasy style, high contrast between deep blacks and blood reds, hand-painted 3D character art, Unreal Engine 5 render, menacing silhouette.
