产品视觉 GPT Image 2 提示词：Black Myth Guan Yu Poster

Epic dark-fantasy poster of {argument name="character name" default="Guan Yu"} reimagined in the style of a mythic action game hero, full-body low-angle composition, towering and dominant in the center, wearing elaborate ancient Chinese battle armor in aged gold and deep green with dragon and beast motifs, massive engraved shoulder guard shaped like a roaring creature, layered lamellar plates, ornate belt clasp, long black hair streaming violently in the wind, and a weathered green headscarf. He holds a long polearm upright in one hand with a dark shaft and red tassel near the blade, while the other hand presents a huge ornate guandao with an intricately carved golden hilt and a broad curved steel blade angled toward the viewer. A huge glowing full moon forms a halo directly behind his head, with a ring of faint ancient Chinese calligraphy arcing around it. Flowing crimson cape and shredded red cloth ribbons whip across the scene, creating strong diagonal motion. The environment is a smoky infernal battlefield with storm clouds, drifting ash, glowing embers, molten red light near the ground, jagged rocks, and colossal shadowy statues or demonic forms emerging in the background. Color palette of burnished gold, ember orange, blood red, charcoal black, and deep jade green. Hyper-detailed cinematic lighting, dramatic rim light from the moon, high contrast, volumetric smoke, richly textured metal, cloth, and hair, ultra-detailed fantasy concept art, premium video game key art, vertical poster design. Include 4 visible text groups integrated like a movie/game poster: the top arched Chinese text around the moon, a mid-lower title line reading "黑神话", an oversized gold brush-calligraphy main title reading "关公", and a bottom tagline line in smaller Chinese characters with a circular emblem at the center.
