秋日黄线列车双面板旅行海报

创作一张受参考图片启发的双面板旅行海报。
上方面板：呈现令人惊叹的写实秋日风景，一列现代黄色观光列车行驶在一座横跨平静湖面的长长高架铁路桥上。画面周围是浓密的金黄色秋树、鲜艳的蓝天、柔软的白云和温暖的阳光；水中清晰映出整列火车、桥梁和树叶。细节丰富、色彩鲜艳，具有电影感旅行摄影风格，光线写实，焦点清晰。

下方面板：将同一场景转化为优雅极简的旅行插画。画出黄色列车驶过高架桥，以干净的海军蓝手绘线条和温暖的金黄色点缀呈现。在列车后方加入一个巨大的金色太阳／圆形，角落以风格化秋叶和枝条构成边框，并添加细致的装饰星星与纤细的水平线，背景为米白色。保留照片中清晰可辨的列车形状与构图，同时赋予精致的编辑风格海报美感。

风格：高端旅行杂志、精致旅游海报、构图简洁、配色和谐、细节丰富、留白均衡、从写实到插画的转化、竖幅4:5版式，不要文字、标志或水印。

Create a two-panel travel poster inspired by the reference images.
Top panel: a breathtaking photorealistic autumn landscape featuring a modern yellow sightseeing train traveling across a long elevated railway bridge over a perfectly calm lake. Surround the scene with dense golden-yellow autumn trees, vivid blue sky, soft white clouds, warm sunlight, and a crystal-clear reflection of the entire train, bridge, and foliage in the water. Highly detailed, vibrant colors, cinematic travel photography, realistic lighting, sharp focus.

Bottom panel: transform the same scene into an elegant minimalist travel illustration. Show the yellow train crossing the elevated bridge, drawn with clean navy-blue hand-drawn linework and warm golden-yellow accents. Add a large golden sun/circle behind the train, stylized autumn leaves and branches framing the corners, subtle decorative stars and fine horizontal lines, and an off-white cream background. Preserve the recognizable train shape and composition from the photograph while giving it a refined editorial poster aesthetic.

Style: premium travel magazine, sophisticated tourism poster, clean composition, harmonious color palette, highly detailed, balanced negative space, realistic-to-illustration transformation, vertical 4:5 layout, no text, no logos, no watermark.
