An IMAX cinematic epic image, Chinese dark fantasy style, an extreme close-up from a low angle, a colossal blood demon phantom skull filling the frame from top to bottom, radiating extreme malevolent menace and a suffocating oppressive terror. The demon skull is a half-solid, half-spectral phantom, its main contour condensed from thick blood essence and demonic energy, its edges wrapped in churning, rising blood-red black mist with a flowing, dissolving quality; its surface is covered in ferocious blood-red demonic markings, protruding black bone spurs and deeply riven cracks that seep a faint blood-red glow. The skull has no complete solid features, only two huge, deep empty eye sockets in which two masses of crimson demon fire burn with tremendous force, the flames bursting and churning violently, sparks and tongues of fire spreading out through the black mist, the scorching red light instantly tearing through the dim frame as the sole core light source and visual focus, the firelight forming a strong contrast across the markings and bone spurs. The background is an utterly deep pure black void, with only scattered points of blood-red light and drifting demonic energy, throwing the skull's menace and terror into maximum relief. 8K ultra HD, extreme detail, cinematic widescreen, strong volumetric light, motion-blurred flames and flowing demonic energy, a low saturation dark palette, a purely fantastical live-action effects image with no figurine, model or statue quality. --ar 16:9 --style raw --v 8
