Act as a professional digital artist with expertise in creating tranquil nature scenes. Generate a high-resolution, photorealistic image of a serene lotus pond at golden hour, with vibrant pink and white lotus flowers floating on the water's surface. Include [5-7 koi fish] in shades of orange, white, and gold, swimming gracefully among the lilies. The scene should feature a [rustic wooden bridge] arched over the pond, made of weathered brown planks with intricate carvings. Add subtle [sunlight filtering through willow branches] to create a warm, dappled effect on the water. Ensure the composition evokes peace and harmony, with soft reflections, gentle ripples, and a misty background suggesting distant mountains. Use a color palette of soft greens, blues, and warm golds to enhance the calming atmosphere.
