Cartoon Lake Scene Inside a Bright School

Cartoon-style classroom scene: a bright, friendly classroom with large windows showing a tranquil cartoon lake outside. Bold outlines, flat colors, and simplified shapes. Students sit at desks, sketching or painting the lake while a teacher points at a poster. Outside the window, the lake has ducks, lily pads, gentle hills, and a sunny blue sky. Inside, a blackboard displays a doodle of the lake and the words 'Our Lake Project'. The overall mood is imaginative, playful, and kid-friendly.
