Regenerate a vibrant circus scene featuring two smiling clowns in colorful costumes in the foreground, with a lively group of people in vintage attire standing under a large striped tent in the background; use a Canon EOS R5 with a 24-70mm f/2.8 lens, aperture set to f/4 for depth of field, ISO 100 for clarity, and a focal length of 35mm to capture the bright colors and joyful atmosphere with soft natural lighting.
