Art style: Реалистичная комедия.
Full-length view, the entire figure visible from head to feet, standing upright, an elderly man named Ivan, centered in the frame. He is around seventy, lean and slightly stooped but sturdy, with a weathered oval face, deep forehead creases, and lively narrowed grey eyes that carry a dry, ironic glint under bushy silver eyebrows. Short thinning silver-grey hair combed back, a neat grey moustache and light stubble. He wears a worn olive-brown cardigan over a checked flannel shirt, faded grey trousers held by a leather belt, and scuffed brown leather slippers. One hand rests in a pocket, the other holds a folded newspaper; his mouth is set in a wry half-smile, one eyebrow raised skeptically. Behind him a cluttered, cozy Soviet-era apartment with bookshelves and warm lamplight. No aura, no glow.
