自信滿滿的女醫生穿比基尼，站在宇宙抽象背景前

A beautiful Caucasian woman in her early 30s with long, wavy auburn hair and a confident, serene facial expression stands in the center of the frame. She has a toned, athletic build and is wearing a white bikini underneath an open white medical lab coat. A teal stethoscope is draped around her neck. Her hands are placed firmly on her hips in a confident pose. She is facing the viewer directly with clear, engaging eyes. The background is a stylized, cosmic-inspired abstract design with swirling shades of deep blue and purple, sprinkled with soft, glowing golden dust particles that add a magical or ethereal quality. The lighting is bright and even, highlighting her features and the smooth texture of her skin. The overall aesthetic is a blend of realistic character illustration and fantasy art, with smooth digital shading and clean lines. The composition is a portrait-style shot focusing on the subject from the thighs up, emphasizing her authoritative yet glamorous appearance against the celestial backdrop.
