โปสเตอร์กวนอูในตำนานดำ

Epic dark fantasy poster, the protagonist is {argument name="character name" default="Guan Yu"}, reimagined in the style of a mythological action game hero. Full body, low-angle composition, centered, tall and mighty. Wearing exquisitely crafted ancient Chinese armor in tarnished gold and deep green, adorned with dragon-beast patterns, massive shoulder pads sculpted into roaring monster shapes, layered scales, a magnificent belt buckle, and long black hair wildly flowing in the wind, wearing a faded green turban. He holds a long-handled weapon upright in one hand, the shaft dark in color, with red tassels tied at the blade; the other hand displays a huge, ornate guan dao, with a beautifully carved hilt and a wide, curved steel blade angled towards the viewer. A huge, luminous full moon forms a halo behind his head, surrounded by a circle of faint ancient Chinese calligraphy. Flowing dark red cloaks and torn red ribbons dance across the screen, creating a strong diagonal dynamic. The environment is a smoke-filled hellish battlefield, with dark clouds, drifting ash, and glowing lava-like red light flickering near the ground, with jagged rocks and massive shadow statues or demonic forms looming in the background. The color scheme uses polished gold, ember orange, blood red, charcoal black, and deep jade green. Ultra-detailed cinematic lighting, dramatic rim lighting from the moonlight, high contrast, volumetric smoke, richly textured metal, fabric, and hair, ultra-detailed fantasy concept art, top-tier video game main visual, vertical poster design. Includes 4 sets of integrated text similar to movie/game posters: arched Chinese text around the moon at the top, a title line “Black Myth” in the middle and lower part, an extra-large golden calligraphy main title “Guan Gong”, and a small Chinese slogan at the bottom with a central circular logo.
