Sunny Autumn Jack Russell in a Cozy Coat

Ultra-detailed photorealistic image of a cheerful Jack Russell Terrier wearing a snug brown-tan tweed coat, sitting among a swirl of vibrant autumn leaves. The scene is a sunny day with clear blue sky; warm sunlight creates bright highlights and soft shadows. Leaves in reds, oranges, golds flutter around the dog, some sparkling with dew. The dog faces the camera with a slight head tilt and bright, expressive eyes. Fur texture is crisp: short white and tan wiry coat; the coat shows woven fabric texture and subtle stitching. Background is a softly blurred park with trees and sunlit bokeh. Camera at the dog's eye level, about a 50mm lens, shallow depth of field, high resolution, cinematic lighting. Mood: joyful, cozy, seasonal. Style: hyper-realistic with rich color grading and tactile textures.
