Why not earlier? At O levels, the focus was on Western art, he says. He still does more still life in the Western style than work derived from Chinese ink.
Over at Nafa, educators say that interest in Chinese ink painting is small compared with that in Western art.
Apart from the full-time diploma in fine arts and bachelor's degree programme, Nafa's Centre for Lifelong Education enrols about 1,000 students in Western art certificate courses in a year. Only about 50 to 60 take up Chinese calligraphy and the same number in Chinese ink painting.
Perhaps students shy away because Chinese ink techniques are much harder to grasp, says established ink painter Quek Kiat Sing. The 46-year-old is also exhibiting at Perceptions and teaches at Nafa's Centre for Lifelong Education.
An award-winning artist who trained in Western art before turning to Chinese ink, she says: "Just mastering the skills and techniques takes a long time. How to hold the brush, how to load the ink - I can show students that every lesson and, still, they will have forgotten the skill by the next lesson."
Ink painter Hong Sek Chern, 50, also cites Singapore's English-speaking environment as a reason for the decline of Chinese ink's popularity. Poetry and calligraphy become more difficult when one is less comfortable in the language. "We don't speak Mandarin that well in Singapore. I'm so-called bilingual, but I have to rely on a dictionary when I read."
A Nafa alumnus, she taught at the school from 1999 to 2006 and recalls years when not a single student signed up to specialise in Chinese ink painting.
Part of the reason is also the global art environment, she says. There are just not that many residencies or scholarships around the world for Chinese ink painters, which means fewer opportunities for students who want to establish themselves.
Recognising this, Nafa recently revamped its tertiary-level curriculum to ensure that students do not merely study one specialisation, as in Hong's time. Students doing Chinese ink have to try other practices.
Currently, there are fewer than 10 tertiary-level students at Nafa specialising in Chinese ink.
Interestingly, not all are Chinese. One of the most promising names is Nur Hikmah Mohamed Tahir, or "Emma", a 23-year-old skate-boarding, hijab-wearing ink enthusiast whose work We Are More Than Our Veil melds Arabic calligraphy with a self-portrait in Chinese ink.
