Minh Họa Vector Phẳng Hàng Chờ Tối Giản

Minimalist flat vector illustration of [four people] standing in a line as if waiting in a queue, all depicted in left-facing side profiles against a solid warm off-white background. Simple editorial style featuring clean, thick dark charcoal outlines, flat muted colors, and minimal facial details. From left to right, exactly four discrete human figures: 1. A young man in a black jacket and black pants, wearing a rounded black backpack, standing upright with arms down. 2. A young woman with dark hair tied in a ponytail, wearing a [muted blue] long-sleeve top, slim black pants, black shoes, and carrying a black crossbody bag. 3. A young man in an all-black outfit with a black backpack, holding a smartphone at chest height while looking slightly downward. 4. A young woman with shoulder-length dark hair, wearing a [muted blue] top, long black skirt, and black shoes, carrying a white canvas tote bag over one shoulder, slightly cropped at the right frame edge. Composition: evenly spaced figures, clean horizontal alignment, no background scenery, no shadows, no text. Restrained color palette of [muted blue], black, charcoal gray, white, and cream, evoking a calm and modern urban atmosphere.
