This is an Oil on canvas painting by a Chinese contemporary artist named Guo Wei.
The first obvious difference is in the style of art that each artists are from. WGY is a political pop artist whereas GW is a contemporary realist artist. The obvious difference is thus the fact that GW does not use previously available artworks and just incorporate it in his artwork like WGY. This means that their technique of delivering the message of the artwork would be different. WGY intentionally uses 'ready-made' picture which are symbolic of the Chinese ideology in Mao's Regime and paste it against modern consumer brands to deliver his message. Thus WGY uses symbolic images and juxtapositions them to create a complex content. However GW creates his own composition and it is his unique form of composition that is his technique. He tends to isolate people in their everyday life situations in an unrecognizable background. He paints these people from a bended perspective which does not seem comfortable and use it as a method of studying who these people are and what they are going through in modern China.
They are similar in their use of humans in their paintings to create a commentary on today's Chinese society and culture. They seem to be both centered around the effects and facts about the Chinese people rather than the nation or the environment. However they have different focuses in which they talk about he people. WGY talks about people collectively as a community and how transformations are widespread across society. In a way WGY deteriorates the individuality of people ( by numbering them) as they conform and integrates with each other and with cultures outside china as well. However WG's focus is especially in the individuals of today's society, especially the restless nature of teenagers. He emphasizes individuality, personality and identity as he tries to express the development of stress in the new liberalizing China. This is in contrast to the 'old' China with extreme communism where the state and community is placed above all. Thus they are also similar in their topic of discussion which is about the cultural revolution of China and how they are more like the western countries.
