Art style: 3D Pixar animation.
Full-length view, the entire figure visible from head to feet, standing upright and centered — Mark, a young father in his early thirties, tall with a lean athletic build, broad shoulders and a trim waist. He has a warm, kind oval face with fair skin, gentle attentive brown eyes, a soft friendly smile, light stubble along a clean jaw, and a short cropped light-brown haircut. He wears a fitted heather-grey crewneck t-shirt, dark navy slim chinos and clean white low-top sneakers. His posture is relaxed and approachable, arms slightly open as if greeting a child, weight balanced evenly. Behind him is a bright, tidy modern family living room with a soft beige sofa, a small potted plant and warm morning light spilling through a large window.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D Pixar animation" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Pixar animation". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "3D Pixar animation" idiom, not in any other medium.
