Create a peaceful park scene designed for retirees. The park should feature tall, lush trees with a variety of green tones, providing ample shade and a sense of tranquility. There should be well-maintained pathways winding through the park, with benches placed strategically under the trees for relaxation. A serene pond with clear, calm water should be in the center, surrounded by colorful flowers and soft, green grass. The sky is clear, with a few fluffy white clouds. A few elderly people are seen walking slowly, sitting on benches, or chatting quietly, enjoying the peaceful environment. The overall atmosphere is calm, welcoming, and ideal for quiet reflection. --ar 16:9
