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艺术作品，描绘不同人们参与日常活动的黑线画。每个角色应独立且不相连，旁边有简短的手写描述。画作应具有松散、自发的风格，捕捉人们在各种场景中的快速素描，如一个人在阅读、有人遛狗、街头艺术家在工作和一个人在咖啡馆吃东西。整体构图应显得随意和非结构化，每个角色独立存在，类似于Jason Polan的素描风格。
