"Generate a realistic digital image of a two-story library with a courtyard in the middle. The ground floor should depict a bustling art gallery, with various artworks on display and people milling about. Make this area chaotic yet vibrant. The upper floor should showcase serene study areas with individuals quietly reading or studying. Ensure the atmosphere on this floor is calm and conducive to concentration. The courtyard should be visible from both floors, providing a tranquil outdoor space amidst the library's activity. Pay attention to details such as lighting, architecture, and the arrangement of books and furniture to enhance the overall ambiance of the scene."
