Art style: Vintage Storybook.
Крупный план: бумажный самолётик в руках дедушки. Фон начинает медленно размываться, и цвета парка сменяются серо-коричневыми тонами окопа. Происходит визуальный переход во времени.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Vintage Storybook" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Vintage Storybook".
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 "Vintage Storybook" idiom, not in any other medium.
