Art style: 3D Pixar.
A high-quality 3D animated movie frame. Pixar style. Medium close-up of Arthur. He steps forward into the light of the fire, looking mature, calm, and incredibly determined. The naive boy from the first episode is completely gone. He places a calming hand out toward Buz (off-screen). The lighting highlights his golden skin and the determined fire in his eyes.

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" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D Pixar". 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" idiom, not in any other medium.
