Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright and centered in the narrow corridor of a Russian sleeper train car, wood-panelled walls, small curtained windows and a red carpet runner filling the sides. A perpetually grumpy but comically endearing middle-aged male passenger from compartment No. 4: rounded pear-shaped build, short stature, slightly stooped posture. Round balding head with a grey comb-over, thick bushy eyebrows knotted in a frown, small squinting eyes, a bulbous nose, a short salt-and-pepper moustache, ruddy full cheeks. He wears a saggy blue-and-white striped tracksuit, an unbuttoned brown cardigan, dark socks, and worn leather house slippers. In one hand he clutches an empty tin tea glass in a metal podstakannik holder, jabbing the other index finger forward in mid-complaint, mouth open mid-grumble, brows raised in exaggerated indignation.
