Birthday in Space

stella_(mikai_inc.), a cheerful young woman with bright eyes and a radiant smile floats gracefully inside her spaceship, holding a glowing birthday cake adorned with candles that flicker like distant stars. Tiny motes of confetti drift lazily around her in the zero-gravity environment, catching the warm ambient light. Her expression beams with pure joy as she celebrates this momentous occasion, with faint silhouettes of her friends visible in the softly lit background. The scene is rendered in a vibrant painterly anime style, with rich colors and intricate details that evoke a sense of wonder and festivity. The soft glow of the candles casts delicate highlights on her face and the surrounding metallic surfaces of the spaceship interior.
