Retro Japanese travel poster: GPT Image 2 prompt

A refined Japanese-style illustration in a vintage travel poster style, featuring [xxx] as the subject. The subject should have a high-end Japanese fashion illustration look, with an elegant silhouette, elongated proportions, a cool restrained expression, and delicate details without becoming overly realistic. Use refined cel shading with broad flat color blocks to shape the form. The palette is built around coral-pink sky, deep navy shadows, dark teal midtones, and ivory-white highlights, restrained yet vivid. The overall mood is quiet, lonely, nostalgic, translucent, and fashionable, like a fusion of a premium magazine cover and a mid-20th-century travel poster. No text, no watermark, no logo, no photographic feel, no 3D, no complex background, no heavy impasto painting, no childish cartoon style.
