Create a minimalist artwork on a plain white background, with black line drawings of different people engaged in everyday activities. Each character should be isolated and unconnected, with a short handwritten description next to them. The drawings should have a loose, spontaneous style, capturing quick sketches of people in various scenarios, such as a person reading, someone walking their dog, a street artist at work, and a person eating at a café. The overall composition should feel casual and unstructured, with each figure standing alone, much like Jason Polan's sketches. --ar 9:16 --quality 2 --v 6.1

在纯白背景上创作一幅极简主义艺术作品，用黑色线条绘制不同人们日常活动的场景。每个角色应独立且不相连，旁边附有简短的手写描述。这些画作应具有松散、自发的风格，捕捉人们在各种情境下的快速素描，例如一个人在阅读、有人遛狗、一名街头艺术家在创作，和一个人在咖啡馆吃东西。整体构图应感觉随意且松散，每个角色独立存在，类似于Jason Polan的素描。
