创作一张高级感的竖版旅行日志海报，采用精确的 50/50 上下分栏。

Create a premium vertical travel-journal poster in an exact 50/50 split. Top 50%: Keep the original reference photo completely real and unchanged same composition, architecture, people, colors, lighting, perspective, and details. Bottom 50%: Transform the same photo into a delicate hand-drawn colored-pencil + watercolor sketch on warm cream paper, with visible pencil strokes, soft washes, subtle paper grain, imperfect outlines, and gentle cross-hatching. Keep every subject recognizable. Add elegant handwritten text: “A Beautiful Day” above and “Memories to Keep” below. Minimal, nostalgic, sophisticated travel-magazine aesthetic. No extra objects, no photorealism in the bottom half, exact 50/50 layout.

创作一张高级感的竖版旅行日志海报，采用精确的 50/50 上下分栏。 上半部分 50%：完全保留原始参考照片的真实原貌，不做任何修改 —— 保持相同的构图、建筑、人物、色彩、光线、视角和细节。 下半部分 50%：将同一张照片转换为在温暖米色纸张上的精致手绘彩铅加水彩素描风格，需呈现可见的铅笔笔触、柔和的水彩晕染、细微的纸张纹理、不完美的线条轮廓以及轻柔的交叉排线。所有主体必须依然可辨识。 添加优雅的手写文字：上方写 “A Beautiful Day”，下方写 “Memories to Keep”。整体呈现极简、怀旧、精致的高级旅行杂志美感。不添加任何额外物体，下半部分绝不可出现照片级写实效果，保持严格的 50/50 布局。
