Create a vertical watercolor travel journal illustration on warm off-white textured paper, showing {argument name="destination" default="Hong Kong"} at {argument name="specific location" default="Victoria Harbour"}. At the top, leave airy negative space and add exactly 2 handwritten text elements: a large loose black ink calligraphy title reading “{argument name="main title" default="Hong Kong"}” and a smaller subtitle beneath it reading “{argument name="subtitle" default="Victoria Harbour"}”. The scene is a dreamy evening harbour view with soft blue-gray mountain silhouettes and misty clouds behind a dense skyline of high-rise buildings, including one very tall rectangular tower on the left and multiple illuminated towers across the center and right. Paint shimmering dark blue water with broken yellow, white, and red reflections. Include exactly 1 large white ferry on the left foreground, angled slightly toward the viewer, with sketchy black ink outlines and warm lit windows. In the right foreground, place exactly 1 stylish young man leaning against a waterfront railing, wearing {argument name="outfit" default="black oversized leather jacket, white T-shirt, dark sunglasses, necklace, rings"}; he has short black hair, a relaxed cool expression, one arm resting on the railing and the other hand raised near his face in a casual gesture. Use a loose urban sketching style: transparent watercolor washes, visible paper grain, splattered edges, imperfect pen lines, minimal facial detail, luminous city lights, and a balanced composition where the person overlaps the harbour while the title remains clean and readable. No photorealism, no hard digital gradients, no extra text, no watermark.
