An editorial travel illustration of Ho Chi Minh City in a simple, charming hand-drawn style, as if sketched with a black ink pen in a travel journal. The illustration feels personal, spontaneous, and imperfect rather than digitally engineered—like a drawing made while sitting at a local café.

Palette: Almost entirely black and white, using only one accent color: sky blue. Apply the blue color sparingly to selected details like a piece of the sky, a window, a street sign, or clothing highlights. No gradients, no heavy shadows.

Subject & Composition: Feature iconic elements of Ho Chi Minh City simplified into flat shapes with minimal interior details: Ben Thanh Market, Notre-Dame Cathedral, buzzing motorbikes on the street, and a glass of Vietnamese iced coffee (cà phê sữa đá). Arrange them into a balanced editorial composition with ample white space. The layout should feel open, light, and airy, allowing objects to overlap naturally without looking crowded.

Mood: Warm, friendly, relaxed, minimalist, and editorial.

CRITICAL: No photorealism. No 3D rendering. No clean vector graphics. Maintain a flat, editorial doodle aesthetic with a clear handmade character.
