May I ask which artist's work this is?

Japanese artist? Takashi Murakami

"One of the most influential Japanese artists born after the 1960s, Takashi Murakami is not only a widely loved artist in Japan, but also an idol for the new generation of Japanese youth.

He strongly realizes that Western contemporary art is very different from Japanese art creation, and that what is important is how our generation can create the most essential things without relying on any inherent cultural system. His work thus combines elements of the opposites between Eastern traditions and Western civilization, between high art and popular culture, while retaining the entertaining and ornamental qualities of his work. It is a product of combining the contemporary Japanese popular cartoon art with the characteristics of traditional Japanese painting style. The fun nature of his work is very noteworthy. Takashi Murakami implanted a variant image of Mickey Mouse into his work (Mr. DOB) seeing it as his own incarnation and a unique visual symbol."
