Crystal Ball in a Castle Courtyard

A vibrant cartoon-style illustration of a crystal ball resting on a wooden pedestal in a castle courtyard. Thick black outlines and bright, saturated colors. Surrounding stone walls, creeping ivy, fluttering banners, torches, and a stone fountain. The crystal ball glows with swirling blue and purple magic, casting playful reflections on the cobblestones. A cheerful wizard in a colorful robe and oversized hat stands beside the pedestal, pointing at the ball as if revealing a secret. Warm sunlight mixes with a soft moonlit glow from the ball, creating a magical atmosphere. The scene is whimsical, with exaggerated cartoon proportions and clean shading, suitable for a kids' book cover.
