Très bien, voici la traduction en français de votre texte, en respectant toutes vos instructions : --- Ultra-Realiste Royaume Céleste Chinois avec Dragon

Create a 9:16 ultra-realistic Chinese mythological celestial realm. A tiny lone traveler stands near the bottom foreground, seen from behind, wearing flowing white robes with subtle red accents. Ahead is an impossibly vast heavenly world: ornate red-and-gold palaces, white-jade stairs and platforms, green glazed roofs, floating mountains, bridges, waterfalls and multiple layers of clouds extending deep into the distance. A colossal Chinese dragon dominates the upper sky, far larger than the surrounding palace districts. Show the head and a long section of its body, while other parts disappear behind clouds and architecture. Build strong foreground / midground / background layering. Use the tiny human as the scale anchor and partial occlusion to make the dragon and celestial architecture feel impossibly huge. Photorealistic mythological environment, cinematic VFX realism, realistic materials and lighting, deep atmospheric perspective, gigantic volumetric clouds. No anime, no cartoon, no game CG, no text, no logo, no watermark. You can swap the dragon color, architecture and spatial structure for each shot.
