Art style: 3D Pixar.
An elderly, eccentric wizard with a long, flowing silver beard that reaches his waist and twinkling violet eyes behind half-moon spectacles. He wears voluminous indigo robes embroidered with shimmering gold constellations and a tall, slightly floppy pointed hat. He carries a gnarled wooden staff topped with a glowing crystal. He stands in the center of a sunlit magical academy classroom, surrounded by shelves of bubbling potions and ancient leather-bound books. His presence is warm and commanding, yet filled with kindly humor and a touch of absent-mindedness.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image in the following art style:
Pixar-style 3D computer animation (Pixar / Disney feature-film look) — fully volumetric 3D rendering with rounded dimensional forms, soft subsurface-scattering skin, physically based materials, soft global illumination, warm cinematic key light, gentle depth of field, vibrant family-friendly colours. CRITICAL: EVERY element — characters, foliage, trees, animals, water, sky, props and the entire environment — must be rendered as polished 3D CGI with real depth and form. This is NOT flat 2D illustration, NOT a watercolour or storybook painting, NOT cel-shaded anime.
Every surface, skin, fabric, material, and environmental element must be rendered in this idiom.
