城市繁忙交叉口水彩速写提示词

Create a loose urban-sketch watercolour of a busy street crossing in {CITY}, vertical 3:4, on pure bright-white cold-press paper with visible texture. No cream, beige, sepia, or vintage tint.

TITLE: Paint only “{CITY}” across the empty upper sky in large expressive hand-lettering. Use translucent warm-grey watercolour with varied brush weight, darker pooling, dry-brush gaps, an irregular baseline, and slight tonal fade. It must look hand-painted with the same brush as the artwork, never printed or pasted. Add a subtle pale blue/apricot wash behind it, fading before the edges.

SCENE: Low-angle pavement view of a wide multi-lane crossing. Make {HERO} the dominant middle-distance landmark, with distinct {LEFT}, {RIGHT}, and smaller {FAR} buildings. Include {VEHICLE}, a few sedans, and one small {PUNCH} vehicle. Keep buildings clearly different in height, material, and colour.

LINEWORK: Rough black fineliner drawn first: loose, wobbly, broken freehand strokes, imperfect perspective, occasional overshoots, and minimal single-direction hatching. No perfectly ruled lines.

DEPTH: Strong density gradient. Foreground is about 60% resolved and colourful; mid-ground about 30% with softened edges; distance about 10%, mostly pale outlines and washes. Leave some distant buildings unpainted. The outer 20% of every edge and all four corners must remain untouched white paper. Never create an even wash or vignette.

ARCHITECTURE: Avoid complete window grids. {HERO} gets only a few broken mullion lines with large areas of wash-only glass. Its glass reflects broad sky-blue and white-paper sweeps, warm apricot sunlight, and only two soft warped building reflections.

PEOPLE: 10–12 figures scattered across near, middle, and far distances. Vary size, spacing, overlap, poses, and activities. Use tiny loose ink marks for distant figures; minimal facial detail; soft grey contact shadows; let some outlines dissolve into the washes.

GROUND: Darker visual weight in the bottom fifth: near kerb, sparse pavement joints, grit, and a cast shadow toward the viewer. Paint only portions of the crosswalk, leaving large areas of white paper.

COLOUR & LIGHT: Loose off-register watercolour over ink with wet-in-wet blooms, backruns, hard edges, and dry-brush skips. Use {WARM} for sunlit architecture/pavement, muted sage for trees, and cerulean for sky/glass. At least four distinct hues; no hue dominates. {PUNCH} is a tiny accent under 3%. White paper is the brightest value. Keep only 4–5 small deepest-value accents.

SKY & TREES: Mostly white sky with sparse broken blue strokes. Trees appear in separated clusters with wide white gaps; vary their size and treatment, including one large cropped foreground tree.

SIGNAGE: All signs are abstract and illegible. No readable text besides {CITY}.

AVOID: photorealism, digital/vector style, glossy 3D, uniform detail, full background washes, solid-black lettering, complete window grids, straight ruled geometry, continuous tree rows, detailed distant buildings, fully painted crosswalk, cream/sepia paper, borders, frames, signatures, logos, or watermarks.

在纯亮白、有可见纹理的冷压纸上，创作一张{CITY}繁忙十字路口的松散城市速写水彩画，纵横比3:4。不要奶油色、米色、乌贼墨色或复古色调。

标题：仅在空旷的上部天空用大型且富有表现力的手写字体画出“{CITY}”。使用半透明的暖灰色水彩，笔触粗细多变，有较深的积水、干笔留白、不规则的基准线以及轻微的色调退色。它必须看起来是用与作品相同的画笔手绘的，绝不是印刷或粘贴的。在其背后添加微妙的淡蓝色/杏色晕染，并在边缘前淡出。

场景：宽阔多车道交叉口的人行道低角度视图。让{HERO}成为中景的主导地标，伴有明显的{LEFT}、{RIGHT}和较小的{FAR}建筑。包含{VEHICLE}、几辆轿车和一辆小型{PUNCH}车辆。保持建筑在高度、材质和颜色上明显不同。

线条：先用粗糙的黑色针管笔勾勒：松散、摇晃、断裂的徒手笔触，不完美的透视，偶尔的留白，以及极少的单向排线。不要完美的尺子线条。

深度：强烈的密度梯度。前景约60%的清晰度和色彩；中景约30%且边缘软化；远景约10%，主要是浅色轮廓和晕染。让一些远处建筑物不着色。每个边缘的外部20%和所有四个角必须保持空白的白纸。切勿创建均匀的晕染或暗角。

建筑：避免完整的窗格网格。{HERO}只得到几条断裂的窗棂线，大面积仅是晕染的玻璃。其玻璃反射出宽阔的天蓝色和白纸扫尾、温暖的杏色阳光，以及仅有的两个柔软扭曲的建筑物反射。

人物：10–12个形象分散在近、中、远距离。改变大小、间距、重叠、姿势和活动。对远处的人物使用微小的松散墨迹；极简的面部细节；软灰色接触阴影；让一些轮廓溶解在晕染中。

地面：底部五分之一处视觉重量较重：近处的路缘、稀疏的铺路接缝、砂砾以及朝向观察者的投射阴影。仅绘制部分斑马线，留出大面积白纸。

色彩与光影：墨线上方是松散错位的水彩，带有湿接湿的晕染、回流、硬边缘和干笔跳跃。对受光的建筑/路面使用{WARM}，对树木使用柔和的鼠尾草绿，对天空/玻璃使用天蓝色。至少四种截然不同的色调；没有主导色调。{PUNCH}是低于3%的微小点缀。白纸是最亮的明度。仅保留4–5个小的最深明度重点。

天空与树木：主要是白色天空，带有稀疏断裂的蓝色笔触。树木以分开的集群形式出现，有宽阔的白色缝隙；改变它们的大小和处理方式，包括一棵大型裁剪后的前景树。

标识：所有指示牌都是抽象且不可辨认的。除了{CITY}外没有可读文字。

避免：写实主义、数字/矢量风格、光泽3D、均匀的细节、完整的背景晕染、实色黑色字体、完整的窗格网格、直线尺规几何、连续的树排、详细的远景建筑、完全绘制的斑马线、奶油/乌贼墨色纸张、边框、框架、签名、徽标或水印。
