创建一个高级的竖版旅行日记海报，采用精确的 50/50 对半分割布局。

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, proportions, and every original detail. 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 and in the exact same position. Add elegant, artistic handwritten text: “A Day Worth Remembering” above the composition. “Little Moments, Lasting Memories” below the composition. The handwriting should feel personal, graceful, slightly imperfect, and naturally written in a premium travel diary. Minimal, nostalgic, sophisticated travel-magazine aesthetic. No extra objects, no photorealism in the bottom half, no altered subjects, exact 50/50 layout.

创建一个高级的竖版旅行日记海报，采用精确的 50/50 对半分割布局。 上半部分（50%）：完全保留原始参考照片的真实感与原样 —— 保持相同的构图、建筑、人物、色彩、光线、透视、比例以及每一个原始细节。 下半部分（50%）：将同一张照片转化为细腻的手绘作品，采用彩色铅笔加水彩的素描风格，绘制在温暖的米色纸张上，呈现可见的铅笔笔触、柔和的水彩晕染、细微的纸质纹理、不完美的轮廓线条以及柔和的交叉排线。每一个主体都要保持可辨认，并处于完全相同的位置。 添加优雅、艺术化的手写文字： “A Day Worth Remembering”（值得铭记的一天）置于构图上方。 “Little Moments, Lasting Memories”（小小的瞬间，持久的回忆）置于构图下方。 手写文字应给人以个人化、优雅、略带不完美、自然书写的感觉，宛如出自一本高级旅行日记。整体呈现极简、怀旧、精致的旅行杂志美学风格。不添加额外物品，下半部分不使用照片写实风格，不改变任何主体，保持严格的 50/50 布局。
