绘本插画：雨伞下的蜗牛

Picture-book illustration of a cheerful garden snail with a glossy brown-and-cream spiral shell, holding a small blue polka-dot umbrella above its head with one tiny tentacle, the snail with big friendly black eyes and a soft smile, crawling across a large glossy green leaf under gentle rain, raindrops bouncing off the umbrella in sparkling droplets, each drop catching a tiny gleam of light, a red ladybug sheltering under the leaf edge, small puddles on the ground reflecting the gray-blue sky, orange-capped mushrooms and tiny white daisies growing nearby, soft rounded painterly shapes with subtle pencil outlines and gentle crosshatch shading, close-up low-angle composition from the snail's level looking slightly upward, soft diffused overcast daylight from above with even gentle illumination, palette of moss green, slate blue, mushroom orange and cream, gentle cozy storybook mood, delicate hand-drawn charm, high resolution, 4k
