A heartwarming Pixar-style 3D animated scene of a boy’s birthday party

A heartwarming Pixar-style 3D animated scene of a boy’s birthday party. The birthday boy, Dobrynya, has light curly blond hair and big blue eyes. He is slightly taller than his younger brother and is standing in front of a colorful birthday cake with a big red number 4 candle on top. Dobrynya wears a festive shirt, a birthday crown, and has a joyful expression as he prepares to blow out the candles. His younger brother stands next to him, smiling and clapping, with curly golden-blond hair and a toy car in his hand. Their parents stand behind them, smiling warmly. The room is decorated with bright balloons, garlands, and a banner that says "Добрыне — 4!" in playful letters. Confetti fills the air. One is blowing a party horn. The lighting is warm and magical, full of soft glows and Pixar-style expressive cartoon faces.
