Art style: 3D Pixar.
Симпатичная 3D буква 'Б' в стиле Pixar весело стучит по яркому игрушечному барабану. Вокруг разлетаются цветные ноты. Игровая комната на фоне. Стиль Pixar, яркие цвета.

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.
