This study is a practice-based reflection on the modern affect of “urban solitude.” Through the oil-painting cycle City Streetscape, the author investigates how an internal, abstract emotional experience can be translated into concrete visual form. The paper proposes and tests a method termed “visual translation”: a subjective cool-grey palette is used to establish an emotional keynote; closed, alienated compositions construct a psychological field; and artificial, symbolically charged light dramatizes the spiritual narrative. Representative works such as Peeping and Security Booth are analyzed to demonstrate the imbrication of formal language and affective expression. The outcome is a personal methodology that may serve as a reference for artists addressing similar themes and that invites wider scrutiny of the psychic landscape of metropolitan life.
