为 [国家 / 城市 / 地点 / 主题] 创作一张高品质的 2:3 竖版建筑主题旅行明信片。

Create a premium 2:3 vertical architectural travel postcard for [COUNTRY / CITY / LOCATION / SUBJECT]. TEXT-TO-IMAGE ONLY — generate the entire artwork creatively from [COUNTRY / CITY / LOCATION / SUBJECT] alone. No reference image required. CORE CONCEPT Create a sophisticated collectible postcard centered around ONE unmistakable architectural landmark from [COUNTRY / CITY / LOCATION / SUBJECT]. Automatically select the most iconic building, monument, street façade, or structure and make it the sole visual hero. ARCHITECTURAL ART Render the landmark as an exceptionally detailed hand-drawn architectural ink illustration using fine black or graphite lines, precise proportions, delicate hatching, tiny windows, façade details, columns, roofs, cornices, and subtle handmade imperfections. Show the architecture from a slightly dramatic but believable low or three-quarter perspective. Allow tasteful cropping when it strengthens the composition. COLOR Keep most of the landmark as exposed linework and introduce only 2–4 sophisticated colors naturally associated with the destination. Use restrained flat color with muted but clean tones. No gradients or glossy digital rendering. BACKGROUND Use a refined light ivory paper background. Subtly integrate faded archival elements related to the destination: fragments of maps, street plans, contour lines, architectural diagrams, coordinates, handwritten annotations, measurement marks, and restrained local-language details. Keep these elements secondary, delicate, and partially faded so the architecture remains dominant. COMPOSITION Use an asymmetric editorial layout with generous breathing room and the landmark occupying roughly 60–75% of the artwork. Add only a few tiny contextual details such as pedestrians, bicycles, street lamps, trees, tram wires, or local street elements when appropriate. TYPOGRAPHY Add the destination name and, if appropriate, its local-language name in small refined editorial typography. Include a minimal archival-style information strip near the bottom with subtle location or architectural details. FINAL AESTHETIC Architectural sketchbook × museum-shop postcard × archival city document × contemporary editorial design. Intelligent, cultured, collectible, precise, and quietly sophisticated rather than a conventional tourist souvenir. Avoid landmark collages, generic watercolor, cartoon architecture, photorealism, giant typography, souvenir clichés, excessive decoration, heavy sepia filters, muddy colors, random landmarks, excessive distressing, or overly symmetrical layouts. FORMAT: 2:3 vertical, single architectural subject, premium collectible travel postcard.

为 [国家 / 城市 / 地点 / 主题] 创作一张高品质的 2:3 竖版建筑主题旅行明信片。 纯文生图（TEXT-TO-IMAGE ONLY）—— 仅依据 [国家 / 城市 / 地点 / 主题] 本身进行创意生成，无需参考图像。 核心概念 创作一张精致且具收藏价值的明信片，围绕 [国家 / 城市 / 地点 / 主题] 中的一座独一无二的标志性建筑展开。自动选择最具代表性的建筑、纪念碑、街道立面或构筑物，并将其作为画面中唯一的视觉主角。 建筑艺术表现 将这座地标建筑以手工绘制的建筑钢笔（墨水）插画形式进行极致精细的描绘，运用细腻的黑色或石墨线条、精准的比例、柔和的排线、细小的窗户、立面细节、立柱、屋顶、檐口，以及微妙的手工绘制瑕疵。 从略微戏剧化但合理的低视角或四分之三视角展示建筑。在能够强化构图的前提下，允许进行考究的裁切。 色彩 保持建筑主体以线条表现为主，仅引入 2–4 种与目的地自然相关的精致配色。使用克制、干净的平涂色调，整体保持柔和而干净。不得使用渐变或光鲜的数字渲染效果。 背景 使用精致的浅象牙色纸张背景。巧妙融入与目的地相关的褪色档案元素：地图碎片、街巷规划、等高线、建筑制图、坐标、手写注释、测量标记，以及克制使用的地方语言细节。 这些元素必须保持次要、精致且部分褪色，确保建筑始终占据主导地位。 构图 采用非对称的编辑式版式，留有充足的呼吸空间，建筑在画面中占据大约 60–75% 的比例。视情况仅添加少量微小的环境细节，例如行人、自行车、路灯、树木、电车线或当地街道元素。 排版 以精致小巧的编辑式字体添加目的地名称，以及在合适的情况下添加其当地语言名称。在底部附近设置一条极简的档案式信息条，包含克制的地点或建筑细节。 最终美学 建筑写生本 × 博物馆商店明信片 × 档案式城市文献 × 当代编辑式设计。智慧、有文化感、可收藏、精准、含蓄而精致，区别于传统的旅游纪念品。 避免地标拼贴、通用水彩、卡通建筑、照片级写实、巨型字体、纪念品陈词滥调、过度装饰、浓重的褐色滤镜、浑浊的色彩、随机地标、过度做旧或过于对称的版式。 格式：2:3 竖版，单一建筑主题，高品质可收藏旅行明信片。
