Realistic wildlife photography of a red squirrel sitting on a mossy fallen branch in an autumn forest, holding a hazelnut with both paws, tail curled naturally behind the body, alert eyes and calm posture. Vertical 3:4 close wildlife portrait composition, soft blurred woodland background with orange leaves and green moss, no human-made objects. Gentle morning side light reveals natural fur, whiskers and tiny paws, realistic shallow depth of field, crisp but not over-sharpened detail, natural color, no logos, no readable text, no watermark, no fantasy elements, no exaggerated expression.
