Art style: 3D Pixar.
A school courtyard on a bright autumn morning. 7-year-old Arina stands in her school uniform, holding a heavy bouquet of autumn asters and clutching her backpack strap, looking nervous. 15-year-old Nastya is kneeling in front of her, gently adjusting her white hair bow with soft, encouraging eyes. Behind them, their father places a warm hand on Arina's shoulder, and mother smiles.

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.
