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.
