Art style: Moody Digital Realism.
An extreme close-up of a steady human hand placing a single smooth gray river stone firmly onto a polished dark walnut table. The stone rests dead center, casting a crisp shadow. Shot at a low, eye-level angle with shallow depth of field, the background dissolving into soft warm bokeh. A single directional light source from the left rakes across the wood grain, warm amber against deep shadow. The mood is deliberate, grounded, and resolute, conveying quiet authority. Dominant palette of charcoal gray, warm amber, and deep espresso brown.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Moody Digital Realism" style.

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 "Moody Digital Realism" idiom, not in any other medium.
