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

在純白背景上創作一幅極簡藝術作品，描繪不同人們參與日常活動的黑線畫。每個角色應獨立且不相連，旁邊有簡短的手寫描述。畫作應具有鬆散、自發的風格，捕捉人們在各種場景中的快速素描，如一個人在閱讀、有人在遛狗、街頭藝術家在工作和一個人在咖啡館吃東西。整體構圖應顯得隨意和非結構化，每個角色獨立存在，類似於Jason Polan的素描風格。
