Art style: 3D cartoon animation.
A dark bedroom at night. Moonlight shines through a window onto a bed. The red-headed Brother sits beside his yellow-headed Sister, comforting her. Blue-toned shadows and emotional atmosphere.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "3D cartoon animation" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "3D cartoon 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 cartoon animation" idiom, not in any other medium.
Character appearance reference (MUST match exactly):
- Sister: A character with a yellow tulip-shaped head and green skin. As a baby, she is small and fragile. As a child, she wears a simple purple dress and has large, expressive eyes often filled with tears.
- Brother: A character with a red tulip-shaped head and green skin. He has a determined and protective expression. He wears a yellow t-shirt and blue denim overalls. The background varies from a factory to a modern house.
