制作一张高端的竖版旅行日记海报，采用精确的 50/50 分屏布局。

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.

制作一张高端的竖版旅行日记海报，采用精确的 50/50 分屏布局。 上半部分 50%：完全保留原始参考照片的真实原貌，不做任何改动——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暖米色纸张上绘制的精致手绘彩铅 + 水彩素描，呈现可见的铅笔笔触、柔和的水彩晕染、细微的纸张纹理、不完美的轮廓线以及细腻的交叉影线。保持每个主体的可识别性。 加入优雅的手写文字：上方写 “A Beautiful Day”，下方写 “Memories to Keep”。极简、怀旧、考究的旅行杂志美学风格。不要添加额外物体，下半部分不要出现照片级写实效果，严格采用精确的 50/50 布局。
