맑은 날 색칠공부 도안

Detailed semi-realistic coloring book illustration of a sunny day with clouds smiling happily. Clean confident black outlines with fine detailed linework (fur, hair, fabric folds, texture, background elements), soft delicate greyscale shading throughout for gentle depth and volume — not flat, not overly simple. Expressive friendly face with refined proportions (not toddler-simple/not baby-round), big detailed eyes. Light clean background with a few environmental details. Only about 10-15 percent of small areas vividly colored as a bold, eye-catching accent (a saturated pop of color on one or two small features, like a bright eye, a flower, a small object), the rest stays black-and-white linework with light greyscale shading — NOT flat fully-colored cartoon, NOT plain grayscale-only, a striking mostly-monochrome page with a few vivid color highlights. Coloring page style aimed at older kids and teens (ages 8-13). No text, no watermark. Vertical A4 portrait orientation.
