A group photo of diverse volunteers wearing matching purple City2Surf t-shirts, standing on a beach with Sydney Opera House and Sydney Harbour Bridge in the background. The volunteers are smiling, some making peace signs, with natural lighting under a bright sunny sky. The image should have realistic human features, skin tones, and facial expressions, capturing a wide range of ages and ethnicities. The iconic Sydney landmarks and beach environment should look highly realistic, with subtle reflections on the water and shadows cast by the sun. Ensure the group is evenly distributed across the beach, with a warm and inviting atmosphere, and natural lighting effects highlighting the volunteers and background details. Maintain the same pose, arrangement, and layout as the original image while enhancing realism
