Affiche dreamcore océan avec typographie chinoise

Generate a vertical 3:4 art poster that must be a fully laid-out, finished poster. The theme is 【fill in theme】. Overall it is neither ordinary ocean photography nor an ordinary fish illustration, but a concept poster with a strong emotional character, dreamlike quality, atmosphere, and design sense. 【Core image】 The main subject is 【school of fish / jellyfish / tropical fish / glowing fish / translucent sea creatures / floating objects / light and shadow on the sea surface】, but it must be heavily reimagined — do not replicate it realistically; transform it into an image with greater visual impact and artistry. You may add: hazy mist, gradient seawater, floating particles, soft focus, light halos, slight grain, blurred edges, dreamcore atmosphere, low-contrast background, ethereal negative space, floating composition, and poetic visual narrative. 【Composition requirements】 The image must have a clear visual focal point. You may use: large areas of negative space, off-center composition, floating layout, poster-style cropping, distinct upper/lower layers, rhythmic density and sparseness of the subject, partial magnification, near/far contrast, title set to one side, and information set in the corners. Don't make an ordinary wallpaper; make it look like a real design poster. 【Color and atmosphere】 The palette centers on 【fill in main color, e.g. coral orange, misty pink, sea-salt blue, deep-sea black, neon purple, gray-green, amber gold】. Unified, soft tones with an airy feel; it may carry a bit of film grain, matte texture, and slight print feel. Atmosphere keywords: quiet, ethereal, melancholic, healing, hazy, dreamlike, surreal, poetic. 【Typography】 Add complete Chinese typography to the image. Main title: 【fill in Chinese main title】 Subtitle: 【fill in a short line of copy】 Small auxiliary text: 【fill in small text 1】 【fill in small text 2】 【fill in small text 3】 The typography should be restrained and refined — no ad-like feel, no clutter, no long manual-style blocks of text. A small amount of English text may accompany it as auxiliary information, but Chinese should dominate. No real brand names, no watermark, no garbled characters, no expired dates. If a date is needed, do not auto-write the year; leave it blank or downplay it. 【Image texture】 High-end art-poster texture, soft-focus photographic feel, dreamy ocean atmosphere, with print grain and a modern design sense. The subject is clear but its edges may be softened; avoid mess, deformation, low quality, and cheap special-effect looks. Output: a complete finished poster, with clear Chinese text and completed layout.
