Art style: Children's Book.
An immense, majestic Great Gray Owl with a massive wingspan and a dense, multi-layered coat of feathers in shades of silver, slate, and charcoal. His facial disc is large and perfectly circular, featuring concentric rings of gray and white that draw attention to his piercing, golden-yellow eyes with deep black pupils. He has a sharp, hooked beak the color of polished obsidian. His talons are thick, powerful, and covered in fine, downy white feathers that transition into rough, scaly gray skin near the sharp tips. He exudes an aura of ancient wisdom and dormant power, perched regally within a dark, moss-lined tree hollow that is illuminated by a faint, ambient blue moonlight reflecting off the surrounding snow.

Render this image entirely in "Children's Book" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Children's Book". 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 "Children's Book" idiom, not in any other medium.
