Create a whimsical children's picture-book illustration in a rough hand-painted gouache/oil-pastel style on a 4:3 horizontal canvas. Show a large {argument name="animal character" default="cheetah"} in the left foreground, sitting on a gray-brown rock ledge and facing right, with a rounded cartoon body, golden-yellow fur, many black spots, a striped tail curled around the rock, a white muzzle, and very thick uneven black outlines like crayon or marker. The cheetah is looking across a sunny African savanna toward exactly 4 zebras in the mid-distance on the right, each small, black-and-white striped, walking in a loose line. Add exactly 3 white sky clouds with heavy black outlines: one medium cloud near the top center, one large long cloud near the top right, and one small cloud near the horizon. Above the cheetah's head place a large white cloud-shaped thought bubble with black outline, connected by exactly 2 small thought circles, containing bold black Japanese text: {argument name="thought bubble text" default="前菜、主菜、副菜、デザート…"}. The landscape should have a bright cyan-blue textured sky, a golden-yellow grassy plain with scattered scrub brush, one flat-topped acacia tree on the right horizon, dark green foliage and a tilted tree trunk at the far left edge, and spiky green grass in the lower right foreground. Use visible brush texture, thick impasto-like strokes, playful imperfect shapes, high saturation, simple composition, and a storybook mood, as if it could be a page from a picture book. Avoid photorealism, gradients, thin clean vector lines, extra animals, or extra text.
