Design works: 1. It is also an act of subjectively looking at things and imagining things. But it doesn't express the author's feelings, but it touches the viewer's feelings. Have a purpose. (For example: various trademarks, decorations, wallpaper, shoe styles ...) 2. Conceptual design. Similar to pure art, but different. (e.g. concept building, concept car ...)

Art: the act of treating things subjectively and imagining things. Appearance is the author's feeling, and it is also what the viewer can feel. (Example: Picasso's self-portrait shows the author's inner sadness at that time. His color, his pen and his content can make us feel this feeling. )
