Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, standing upright and centered, an elderly man named Ivan Petrovich with a kind, gentle face. He is in his early seventies, with a softly rounded face, warm fair skin lined with friendly wrinkles, rosy cheeks, bushy grey eyebrows, and clear blue eyes that look slightly anxious. He has thinning silver-grey hair combed back and a neat short white moustache. His build is a little stout and stooped, with rounded shoulders. He wears a buttoned beige cardigan over a pale blue shirt, dark grey trousers, and soft brown leather slippers. One sleeve is slightly rolled up near the forearm. His hands are clasped nervously in front of him, posture mildly uneasy. Behind him a clean, bright medical clinic room with a reclining treatment chair and softly glowing equipment.
