Prompt: Create an illustration of a 3D Pixar-style cartoon scene. Iris, with black waist-length hair and reddish-brown eyes, wearing a white T-shirt, a blue denim jacket, and black jeans, adorned with cross earrings, stands at the front of a classroom filled with American elementary school students. The classroom is vibrant and welcoming, adorned with educational posters and colorful decorations. Iris, with a warm and encouraging smile, engages the students in a lively lesson. She might be holding a chalk or marker, explaining a fascinating concept on a whiteboard or using interactive tools to make the class engaging. The diverse group of American students is seated at their desks, eagerly participating in the lesson. Some raise their hands enthusiastically, while others discuss amongst themselves in excitement. One student might be showcasing a project they've been working on, while another eagerly listens and takes notes. Iris's passion for teaching radiates through her animated gestures and expressions, making the learning environment enjoyable and stimulating. The scene captures the essence of a dynamic and engaging classroom where both the teacher and students are actively involved in the educational experience.
