Art style: 3D Pixar.
The bright blue sky over the park. Suddenly, a massive, swirling gray cloud begins to creep across the frame from the right side, blocking out the sun. The bright rainbow is visible in the background. Low angle shot looking up at the sky. The lighting shifts from bright and sunny to dim and ominous. The atmosphere becomes tense and sudden. Dark grays, deep blues, and faded primary colors.

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.
