His first foray into the comic industry was the release of It Takes a Wizard, a 480-page single volume manga, written by German writer Thomas R. Hart, and published by Seven Seas Entertainment, an American publisher of original manga-style comics in 2009. Two years later Macmillan Publishers published his two-part graphic novel adaption of the sci-fi novel Ringworld by Larry Niven, namely Ringworld: The Graphic Novel, Part One and Ringworld: The Graphic Novel, Part Two. He then went on to develop several bible-themed graphic novels with American publisher Manga Hero, which includes Paul: Tarsus to Redemption,Judith: Captive to Conqueror, Many Are Called, and Habemus Papam! manga. He released a 32-page Pope Benedict manga comic which was distributed in August during World Youth Day 2011 in Madrid. This was followed by an expanded version of the graphic novel which went deeper into the life of Pope Benedict XVI. In 2012 he won an award for his bible themed graphic novel, Judith: Captive to Conqueror at Angoulême Christian Comics Festival in France. A 48-page paperback, Pope Francis: I Believe in Mercy,, was later created to celebrate the appointment of Pope Francis. In 2015 he collaborated with the Four Lords from San Diego as the main comic artist for The Curseborn Saga manga, and together held a book signing at the Los Angeles Anime Expo for the launch of the first volume, followed by another at the San Diego Comic-Con, where his team got an exclusive interview by ABC 10 News. They are currently in works on the second volume of the comic and an art book with a consolidation of all his current concept arts and character designs for the story planned for release sometimes towards end of 2018 or early 2019. He is also currently working with kingB, an author as well as an artist, to create two new original comic series namely the 'Red Dot' and 'Goddess Punch', both which were introduced exclusively on his social media platform Instagram. Both works aim to appeal to both local Singaporeans as well as the international audience. Apart from working on graphic novels, Sean has held in-house art gallery showcasing his popular online series of 'Red Dot' and 'Silent Night series' artworks which he has also shared on his Instagram. In an interview in 2011, he talked about hopes to bring changes to the art scene in Singapore and to hopefully attract and trigger the creativity in children in comic and manga art, saying “Manga can deliver emotions faithfully and carry a vivid message to readers, evoking a sense of reality in the story. Young children are usually fascinated by the art when they pick up the book. I hope that my artwork can help them understand the emotional background of the set and characters, and bring them into that world to learn about the wonderful stories of faith and goodwill.”
