喷泉水幕中的夏日男孩

在带纹理的冷压手工纸上绘制极简水彩插画，3:4竖构图，大面积留白，细腻的墨线条，半透明的渲染层次，湿中湿晕染，颜料颗粒感，漂浮的水滴，温馨的生活片段感，优雅的编辑质感，博物馆级品质，8K。
色板：钴蓝与天青色的天空，留白纸面表现云朵，暖灰色花岗岩，柠檬黄与薄荷绿点缀。
场景：一个韩国小学男孩从首尔光化门广场的拱形喷泉射流隧道中走出，阳光明媚的夏日里浑身湿透，咧嘴大笑，耸起肩膀，一只手拂去脸上的水，橡胶凉鞋溅起湿润石面上的水花。纯粹的孩童式喜悦。
构图：平视正面视角。男孩位于画面中下三分之一处，身形较小。拱形水柱形成一条向后延伸的墨线拱形隧道，汇聚于他身后柔和的消失点。单一、统一的瞬间。
环境：锚点仅为拱形水柱与湿润花岗岩。男孩与最近的水柱约60%清晰呈现；远处的建筑与树木消融为淡蓝灰色的渲染、破碎的石墨、颜料晕染与未着色的纸面。天空几乎空白。
服装：柠檬黄T恤，薄荷绿短裤，淡蓝色橡胶洞洞鞋，湿发向后梳，脸上与衣服上有细小逼真的水珠。
光线与水：强烈温暖的正午阳光。水柱以细墨线呈现，逐渐碎裂为点状与逗号形水滴，落地处有干笔喷溅效果，淡天青色在花岗岩上积聚。保留大面积未着色的象牙白纸面。无文字、说明文字、标识、标志、水印、重复人物、多余肢体、变形的手、拥挤的背景、暗色数字绘画、粗重轮廓线或有光泽的3D渲染。

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.
