上下双景复古旅行海报

创作一张高级全幅4:5竖版照片转插画旅行海报，主题为[COUNTRY / CITY / LOCATION / SUBJECT]。

仅限文生图——完全依据文字描述的主体生成全部内容，无需参考图。

核心概念：
创作一张充满童趣的复古旅行手记海报，画面精确地水平分割：上方50%呈现写实摄影场景，下方50%将同一场景转化为精美的手绘旅行插画。

构图：
两部分的主体保持一致。上半部分呈现自然光线、真实质感与写实细节。下半部分以简化的形状、柔和的水彩与水粉，以及温暖的奶油色纸张背景重新诠释该场景。

风格：
复古旅行明信片、手绘建筑、精致的植物细节、俏皮的手写字体、细小的星星与爱心，以及微妙的纸张肌理。添加一句简短、有创意的英文标题，以及一个受场景启发的小型目的地标签。

色彩：
暖象牙白、天蓝、柔和的青绿色、明亮的鹅黄、珊瑚色、鼠尾草绿与赤陶色。使用明快、和谐的色彩，营造怀旧的午后氛围。

最终美学：
真实摄影 × 插画式旅行记忆 × 复古编辑设计 × 俏皮的手写排版。

避免：
拼接无关场景、两部分之间更换主体、杂乱、过多文字、光滑的数字艺术、3D、标志、水印和样机。

格式：
精确的4:5竖向比例，全出血画面，完整覆盖画布，清晰的50/50水平分割，高分辨率。

Create a premium FULL-FRAME 4:5 vertical photo-to-illustration travel poster for [COUNTRY / CITY / LOCATION / SUBJECT].

TEXT-TO-IMAGE ONLY — generate everything from the written subject alone. No reference image required.

CORE CONCEPT:
Create a charming vintage travel-journal poster with a precise horizontal split: the upper 50% features a realistic photographic scene, while the lower 50% transforms the SAME scene into a beautiful hand-painted travel illustration.

COMPOSITION:
Keep the main subject consistent across both halves. The upper section features natural lighting, authentic textures, and realistic details. The lower section reimagines the scene using simplified shapes, soft watercolor and gouache, and a warm cream paper background.

STYLE:
Retro travel postcards, hand-painted architecture, delicate botanical details, playful handwritten lettering, tiny stars and hearts, and subtle paper texture. Add a short, creative English headline and a small destination label inspired by the scene.

COLORS:
Warm ivory, sky blue, muted teal, sunny yellow, coral, sage green, and terracotta. Use cheerful, harmonious colors with a nostalgic afternoon atmosphere.

FINAL AESTHETIC:
Real photography × illustrated travel memory × vintage editorial design × playful handwritten typography.

AVOID:
Combining unrelated scenes, changing the main subject between halves, clutter, excessive text, glossy digital art, 3D, logos, watermarks, and mockups.

FORMAT:
Exact 4:5 vertical ratio, full-bleed artwork, complete canvas coverage, clean 50/50 horizontal split, high resolution.
