Cute Watercolor Girl on Nathan Road

Create a vertical watercolor and ink illustration of a young woman standing on a busy city street corner. The style should be cute, hand-drawn, and airy with soft pastel colors and loose black outlines.

Subject details: A girl with long, wavy brown hair stands in the center foreground, looking back over her shoulder at the viewer with a gentle smile. She wears a black sleeveless top, high-waisted white wide-leg trousers, and white sneakers. She carries a black quilted Chanel-style bag with a gold chain strap. Small pink hearts and yellow sparkles float near her head.

Setting: A bustling urban intersection reminiscent of Hong Kong. To the left is a grey traffic light pole with a red light illuminated. Attached to the pole are two signs: a top white sign reading "Nathan Road" and Chinese characters, and a lower pink rectangular sign reading "Sasa" and Chinese characters.

Background elements:
1. Two iconic red taxis are visible—one driving away on the left (license plate 740) and one parked or moving slowly on the right (license plate TX 5037).
2. Tall buildings line the street in the background, rendered in pale blues, creams, and greys.
3. On the right building facade, there is a large white billboard with red text "AD HERE" and Chinese characters, and below it a green shop sign reading "LUKFOOK" and Chinese characters.
4. Faint silhouettes of other pedestrians are sketched in the distance.

Visual style: Use a sketchy, artistic aesthetic with visible pencil lines and watercolor washes that bleed slightly outside the lines. The lighting is bright and cheerful.
