An adorable first-day-of-school graphic. A smiling cartoon kid with a big red backpack waves while standing beside a yellow school bus, autumn leaves drifting and a bright sun overhead. A hand-lettered banner 'First Day, Big Adventure!' runs across the top in navy. Warm, encouraging, playful mood; sunny yellow, red, navy and grass-green palette; soft cartoon illustration, thick outlines, cheerful portrait composition.
