With the fusion of bold sticker symbols, dynamic interplay of texts, and overlapping figures, the artist unravels his travel observations onto the pictorial space. A journey to Hong Kong inspired Khairudin to revitalize his impressions of the various logos and symbols reflecting underground subculture, graffiti art, wireless networks, people, and food (through mandarin words derived from menus). In this work, art and design merge into one another, as it reflects on the process of learning foreign cultures through text and graphic visuals from the surrounding neighbourhood. It also presents a delicate portrayal of figures accompanied by local stickers encountered during his stay. Tranquillity In The Big City is a thoughtful contemplation of urban life materialised on canvas, tracing the rhythms and interactions within the environment.  Khairudin Zainudin has had many solo exhibitions up to date. Besides actively participating in various group exhibitions locally, his works have been exhibited at numerous art fairs such as Art Expo Malaysia, Art Stage Singapore, Art Taipei, Art Kaohsiung, and Bazaar Art Jakarta. His complex figurative composition with lines often captivates the audiences. His recent solo exhibitions NADI (2025), Cerita Orang (2023), and Ambivalence (2021) was held at G13 Gallery. He has participated internationally in shows such as Art Formosa with G13 Gallery at Eslite Hotel, Taiwan (2024), Hotel Art Fair Bangkok at the InterContinental Bangkok Sukhumvit, Thailand (2024), and Art Moments Jakarta with G13 Gallery (2019).
