Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Shustrik, a young red squirrel mailman, caught mid-stride as if hurrying. Small rounded body with bright coppery-orange fur, a creamy lighter belly and chest, big expressive amber eyes, round twitching ears tufted with longer orange fur, and a huge fluffy curved tail arcing behind him. He wears a tiny navy-blue postal cap tilted slightly askew, a little mustard-yellow scarf, and a well-worn brown leather satchel far too big for him slung across his back, its flap bursting open with white envelopes and letters spilling and fluttering out mid-air. His tiny paws reach to catch falling mail; one envelope slips from his grip. Energetic, slightly clumsy off-balance pose, cheerful wide-eyed grin. He stands on a misty forest path among tall ferns and dim twilight trees.
