Serena Williams

Chibi-style Serena Williams as a mischievous tennis fairy, with exaggerated big eyes and a playful grin. She's wearing a sparkly, pastel-colored tennis outfit with tiny wings on her back. Her hair is styled in her signature ponytail with colorful tennis ball-shaped hair ties. She's holding an oversized magical tennis racket that's glowing and leaving a trail of stars. The background is a whimsical tennis court with floating tennis balls and trophies. Serena is posed mid-jump, with one leg kicked up behind her. Soft, pastel color palette with pops of neon. Kawaii-inspired details like heart-shaped sweat drops and starry eyes. The overall composition is circular, perfect for a sticker format. Add a subtle shimmer effect and a thin white border around the entire image. Use clean, bold linework and flat colors for a crisp, sticker-like appearance.
