여름 수박 색칠공부 도안

Detailed semi-realistic coloring book illustration of a summer watermelon picnic 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.
