创作一幅高级感的 4:5 竖版旅行写生作品，以[国家 / 城市 / 地点 / 地标]为主题，画在一本小巧的水彩写生本上。

Create a premium 4:5 vertical on-location travel sketch of [COUNTRY / CITY / LOCATION / LANDMARK], drawn in a small artist’s watercolor sketchbook. TEXT-TO-IMAGE ONLY — generate the entire scene creatively from [COUNTRY / CITY / LOCATION / LANDMARK] alone. No reference image required. CORE CONCEPT Capture the chosen landmark as a spontaneous sketch made directly on location by a skilled travel artist. Preserve its recognizable silhouette, proportions, architecture, and defining features, but interpret them with quick, economical marks rather than fully rendering every detail. COMPOSITION Show ONE natural street-level viewpoint, choosing the most characteristic perspective for the landmark. Include only a small amount of surrounding architecture, greenery, street elements, and a few tiny gestural figures where appropriate. Let the drawing naturally dissolve into untouched white paper around the edges. Keep the landmark as the clear focal point while allowing parts of the scene to remain unfinished. SKETCH STYLE Use loose observational urban-sketch techniques: - light wandering graphite construction lines - occasional confident dark ink accents - quick transparent watercolor washes - visible brushstrokes, blooms and pigment overlaps - irregular, broken and doubled lines - simplified architectural details - areas where watercolor crosses or escapes the linework - generous untouched paper Concentrate detail around the landmark’s most recognizable architectural features and allow secondary areas to fade into suggestive marks. COLOR Use a small, restrained watercolor palette naturally derived from the real landmark and its surroundings. Keep the paper predominantly white and allow subtle variations, uneven washes, and accidental edges to remain visible. FINAL AESTHETIC Authentic travel sketchbook × European urban sketching × loose watercolor × graphite observation × handmade artistic spontaneity. The image should feel like a beautiful 20–30 minute sketch made while sitting in front of the landmark — observant, imperfect, intimate, and alive. Avoid photorealism, polished architectural rendering, overly precise linework, fully painted backgrounds, uniform detail, digital smoothness, heavy shading, excessive colors, decorative borders, text, logos, and watermarks. FORMAT 4:5 vertical, single cohesive sketchbook page, natural street-level perspective, white paper, loose unfinished edges, expressive watercolor and graphite texture.

创作一幅高级感的 4:5 竖版旅行写生作品，以[国家 / 城市 / 地点 / 地标]为主题，画在一本小巧的水彩写生本上。 仅限文生图（TXT2IMG）—— 完全根据[国家 / 城市 / 地点 / 地标]的描述进行创意生成，无需参考图。 核心概念 将由一位技艺娴熟的旅行艺术家在实地现场即兴速写的方式捕捉所选地标。保留其可辨识的轮廓、比例、建筑造型与标志性特征，但以快速、经济的笔触去诠释，而非完整、精细地描绘每一个细节。 构图 选择一个自然真实的街景视角，以最能代表该地标的特征性透视呈现。地标周围仅保留少量周边建筑、绿化、街景元素，必要时点缀几个极小的速写人物。 画面自然向四周的留白纸面淡出消失。地标作为清晰的视觉焦点，同时允许画面中部分区域保持未完成状态。 速写风格 运用松散的观察式城市速写技法： - 轻盈随性的铅笔（石墨）辅助结构线 - 偶尔出现的果断深色墨水点缀 - 快速透明的水彩薄染 - 清晰可见的笔触、晕染与颜料叠加 - 不规则、断续与重复的线条 - 简化的建筑细节 - 水彩越过或溢出线条的区域 - 大量留白未着墨的纸面 在最具辨识度的建筑特征周围集中刻画细节，次要区域逐渐过渡为暗示性的笔触。 色彩 使用从真实地标与环境自然衍生的小巧克制的配色。整体纸面以白色为主，允许细微的色差、不均匀的渲染与偶然的边缘保留可见。 最终美学 真实的旅行写生本 × 欧洲城市速写 × 松散水彩 × 石墨观察 × 手作艺术的自发性。 画面应让人感觉这是一幅在实地坐在地标前完成的 20–30 分钟速写 —— 观察细致、不完美、私密而充满生气。 避免：照片级真实感、精致建筑渲染、过度的精确线条、完整涂满的背景、均匀一致的细节、数字化的平滑感、浓重的阴影、过多的色彩、装饰性边框、文字、logo 以及水印。 格式 4:5 竖版，单一完整的写生本页，自然街景透视，白色纸面，松散未完成的边缘，富有表现力的水彩与石墨质感。
