Vertical watercolor doodle portrait of stylish young woman

9:16 vertical wide-angle composition, with a clean minimalist white background and casual light-blue and pale-purple watercolor brush-stroke doodles. A stylish, cool young woman with long straight jet-black hair blowing in the wind, raising one hand to gently touch the hair on top of her head. She wears rimless gradient sunglasses, pink flower earrings, a white pearl bracelet, and a gold necklace. She is dressed in a bright pink cropped high-neck short-sleeve top, with long rose-magenta manicured nails. Her makeup is vivid and confident, with a carefree, relaxed, effortlessly chic attitude. Sketch-style hand-drawn illustration aesthetic, lively expressive lines, with the subject naturally integrated into the environment. No watermark, no additional text in the image.
