Design a whimsical 3D background image of a magical potions classroom, characterized by a minimalistic and stylized-cartoonish aesthetic. The room is dimly lit, with dark colors creating a cozy yet mysterious atmosphere. Tall, sleek shelves line the walls, filled with an array of potion ingredients—jars of vibrant herbs, colorful powders, and glass bottles of various exaggerated shapes. Each bottle is uniquely designed, showcasing bright colors that pop against the dark background. Soft, ambient lighting bathes the scene, with warm glows emanating from select bottles, casting playful shadows that enhance the magical feel. The overall composition should evoke a sense of wonder and curiosity, inviting players to explore the enchanting world of potion-making in this stylized classroom.
