Create a cheerful childlike wax-crayon illustration on white textured paper in a naive hand-drawn style, using pastel scribbly strokes and soft uneven outlines. Show three storybook children across the upper middle: on the left, a child in a purple wide-brim hat and purple cloak holding a tiny teacup, with the face replaced by a plain beige square; in the center, a boy in a green cap and green jacket with yellow suspenders, touching his mouth thoughtfully; on the right, a smiling child in profile wearing a pink feathered beret and a blue striped shirt with pink-and-black suspenders. Surround them with playful doodles: 2 smiling clouds, 1 smiling sun, 2 smiling yellow stars, 1 plain yellow star, 1 small blue star, 1 purple asterisk star, 2 large flowers, 3 small flowers, 1 teddy bear with a purple bow, 1 lollipop, 1 wrapped candy, 1 tulip, 1 pink ribbon bow, green grass, leafy vines, small dots and curls, and many pink hearts. In the center-lower area place a large scalloped pink crayon frame decorated with green vine flourishes and a bow at the top; inside it write the hand-lettered French quote {argument name="quote" default="Notre tâche la plus importante, pour le moment, est de bâtir des châteaux en Espagne."} in dark gray, with the attribution below in purple and pink: {argument name="attribution" default="Lewis Mumford, The Story of Utopias (1922)"}. Keep the mood whimsical, optimistic, handmade, and nursery-wall friendly, with imperfect crayon texture, rounded cute faces, rosy cheeks, and no photorealism. Copy prompt
