Engaging with the theme of past historical figures, Khairudin employed the technique of scratching and configuring skull motifs on aluminium, enhancing the visual depth of the image. The eye of the figure is prominently featured, as it represents a personal vision that could not be replicated in any way. 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 solo exhibition Cerita Orang was held in 2023.
