He has also provided illustrations for the "Wheel of Time Roleplaying Game" and the "Star Wars" supplements "Secrets of Tatooine", "Ultimate Alien Anthology" and "Star Wars Hero's Guide" and almost two hundred illustrations for the card game. He also contributed to "", a DC Comics graphic novel by Alan Grant. In 2000, Critchlow withdrew from mainstream comics; he wrote and drew the "Thrud the Barbarian" strip for its own comic. The series proved popular with the comic reading public and won the Diamond 2004 Award for Best Small Press title. During this time he also worked as a lecturer and numerous new comics artists, such as Barry Renshaw, credited him for helping and inspiring them. In October 2002, four months after the first issue of "Thrud" was published, Critchlow started drawing for 2000AD again. His first work was the Judge Dredd story "Out of the Undercity" written by John Wagner, followed by the introduction of new comic "Lobster Random" in 2003 with "No Gain, No Pain", written by Simon Spurrier. This was followed by "Tooth & Claw" in 2004 and "The Agony & the Ecstasy" in 2006. His current work includes ongoing artwork for Lobster Random and artwork for Judge Dredd scripts by Gordon Rennie. Critchlow's early work, including the entire "Thrud the Barbarian" series in "White Dwarf", consisted entirely of black and white ink drawings. The Thrud character originated at art college, where Critchlow was studying under comic artist Bryan Talbot.Critchlow was presented with a comic strip project for the course, and began to develop Thrud. Critchlow was inspired by Robert E. Howard's Conan stories, which he was reading at the time. In an exposè published in "White Dwarf" towards the end of Thrud's tenure, art editor John Blanche wrote that Critchlow's "unique, chunky comic book technique provides the perfect vehicle for the biffoesque barbarian." In the 1990s Critchlow began to use colour; his work on the 1995 "Batman/Judge Dredd: The Ultimate Riddle" was fully painted. At the time, while considered impressive his painting work was also considered forced, confused and muddy. Critic Joseph Szadkowski wrote that Critchlow's 1996 work "Sherlock Joker Strikes Out" shows his "commitment to presenting the Joker in an expressionist style, almost [Ernst Ludwig] Kirchner in a good mood."
