Autumn Mallard by the Water's Edge

Photorealistic, high-resolution image of a male mallard duck standing on lush green grass at the edge of a calm lake during autumn. The duck features a glossy emerald-green head, white neck ring, rich chestnut breast, gray-brown body, and vivid orange feet. Surrounding scenery displays rich autumn foliage in golds, ambers, and reds, with fallen leaves scattered on the grass and a mirror-like water surface reflecting the warm colors. Soft, golden-hour sunlight from the left casts long, gentle shadows and gives the scene a warm glow. Slight breeze causes subtle ripples in the water and the duck's feathers to glisten. Use a shallow depth of field to keep the duck in sharp focus while the background is softly blurred (bokeh). Composition places the duck off-center to the left, with water and reeds on the right, capturing a tranquil, seasonal mood. Include fine details: dewy grass, detailed feather texture, water reflections, and a serene atmosphere. Render in 8k quality, photorealistic, natural lighting, and cinematic color grading that emphasizes autumn hues.
