产品视觉 GPT Image 2 提示词：Epic French Dystopian Book Cover

A cinematic French dystopian science-fantasy book cover in vertical poster format, dark and epic, with a cold desaturated palette of charcoal blue, steel gray, ash white, and muted silver. In the foreground, show 1 solitary young traveler seen from behind, standing on a snow-dusted rocky cliff at lower left, small against the environment, wearing a weathered winter jacket, rugged pants, boots, and a large worn backpack, with messy light brown hair visible, posture still and contemplative as he looks out over a vast ruined city. In the middle distance, depict 1 immense circular or sprawling fortified city in a frozen valley, dense with countless dark gothic-industrial buildings and spires, surrounded by icy water channels and connected by several narrow bridges. Rising from the exact center of the city, place 1 colossal needle-like black tower that dominates the skyline, dramatically taller than everything else. Surround the city with jagged snow-covered mountain ranges on both sides and in the far distance. Above, create a stormy sky filled with heavy textured clouds, faint snowfall or drifting ice particles, and a pale backlit glow breaking through behind the central tower, giving a mythic apocalyptic atmosphere. Composition should emphasize scale, isolation, and awe, with the traveler occupying only a small portion of the image and the city and tower centered. Add distressed serif typography integrated as a cover design: at the very top in small uppercase French text, "DANS L’UNIVERS DE APRÈS L’EFFONDREMENT"; below it, a huge title in cracked weathered off-white serif capitals, "{argument name="title text" default="ELON"}", spanning nearly the full width; beneath the title place 1 small compass-star ornament centered with thin horizontal lines. At the bottom center, add the author name in refined serif capitals, "{argument name="author name" default="MARTINOLLI"}". Make the overall image look like premium dark fantasy / post-apocalyptic cover art, ultra-detailed, atmospheric perspective, realistic textures, dramatic lighting, moody, monumental, polished publishing design.
