Minimalist watercolor illustration on textured cold press handmade paper, 3:4 vertical, large negative space, delicate ink line art, translucent washes, wet on wet blooms, pigment granulation, floating droplets, cozy slice of life warmth, elegant editorial quality, museum quality, 8K. PALETTE: cobalt/cerulean sky, bare white paper for clouds, warm grey granite, lemon yellow and mint green accents. SCENE: A single Korean elementary school boy walks out of an arching fountain jet tunnel at Gwanghwamun Plaza, Seoul, on a bright summer day soaked, grinning wide, shoulders lifted, one hand brushing water from his face, rubber sandals splashing wet stone. Pure childlike delight. COMPOSITION: Eye level frontal perspective. Boy small in lower middle third. Arching jets form a receding ink arc tunnel converging to a soft vanishing point behind him. Single cohesive moment. ENVIRONMENT: Anchor = arching jets + wet granite only. Boy and nearest jets ~60% resolved; distant buildings/trees dissolve into pale blue grey washes, broken graphite, pigment blooms, untouched paper. Sky nearly empty. WARDROBE: lemon yellow t shirt, mint green shorts, pale blue rubber clogs, soaked hair pushed back, tiny realistic droplets on face and fabric. LIGHT/WATER: Strong warm midday sun. Jets rendered as fine ink lines breaking into dots and comma shaped droplets, dry brush spray at landing, pale cerulean pooling on granite. Large untouched ivory paper areas preserved. No text, captions, signage, logos, watermarks, duplicated figures, extra limbs, distorted hands, crowded background, dark digital painting, heavy outlines, or glossy 3D rendering.

极简水彩插画，绘于纹理冷压手工纸上，3:4竖构图，大面积留白，精巧墨线艺术，半透明水彩晕染，湿叠湿花青，颜料颗粒沉淀，漂浮水珠，温馨生活切片，优雅编辑级品质，博物馆级品质，8K。 调色板：钴蓝/天蓝天空，裸白纸面留作云朵，暖灰花岗岩，柠檬黄与薄荷绿点缀。 场景：一个韩国小学男生在首尔光化门广场，夏日晴朗的一天，浑身湿透地从一道拱形喷泉水柱隧道中走出，咧嘴大笑，肩膀上扬，一只手拂去脸上的水珠，橡胶凉鞋溅起湿石上的水花。纯粹的孩童喜悦。 构图：平视正面透视。男孩小位于中下三分之一处。拱形水柱形成一条向后延伸的墨线弧形隧道，收敛于其身后柔和的消失点。单一凝聚瞬间。 环境：锚点 = 拱形水柱 + 湿花岗岩，仅此而已。男孩与最近的水柱约60%完成度；远处建筑/树木消融于淡蓝灰水洗、破碎石墨、颜料晕染、未触纸面之中。天空几近空寂。 服装：柠檬黄T恤，薄荷绿短裤，淡蓝色橡胶雨鞋，湿发后梳，面部与衣物上有细小的写实水珠。 光/水：强烈的暖色正午阳光。水柱以细墨线绘制，碎裂为圆点与逗号形水珠，落点处以干笔喷雾表现，淡天蓝在花岗岩上汇聚成洼。大面积象牙白未触纸区域予以保留。禁止出现：文字、说明文字、标识、标志、水印、重复人物、多余肢体、扭曲双手、拥挤背景、深色数字绘画、浓重轮廓线，或光泽3D渲染。
