He is an artist who combines painting, photography and digital art[citation needed] and as well as his work in comics, he has provided the art for role-playing games and collectible cards.
Langley's first published work was with Nighfall Games's role-playing game SLA Industries in 1993. His work appeared in their first three books, SLA Industries, Karma and Mort, for which he painted the cover. He also provided the large wrap-around painting for the game's GM's screen. He returned to SLA Industries in 2019, contributing 3 pieces, including the back cover art, to the source book: Cannibal Sector One.
He has since repeatedly collaborated with Mills, most notably on his long-running series ABC Warriors and Sláine where he is the current artist on both. Mills also has formed Repeat Offenders with Langley and Jeremy Davis "to develop graphic novel concepts with big-screen potential" and the first project was a graphic novel called American Reaper. It has been optioned by Trudie Styler's Xingu Films and Mills will be writing the screenplay.[1]
Since 2007 he has also got work in the American comic book market providing covers for Marvel Comics, especially those connected with Dan Abnett, who he worked with on Sinister Dexter, leading to a run on the modern incarnation of the Guardians of the Galaxy.
