The feature of Takashi Nanase’s artworks is the ambiguity of "border". The artwork itself can be seen as a photo or watercolor painting. Each of the drawn objects seems to exist in reality but does not exist. Are those things real? or are they in the dream? He thinks that the more ambiguous the boundary is, the more reality can be revealed and the existence of “himself” can be depicted more clearly. He thinks using digital as the tool for creating art is the best way to present her concept of art.
