For some time after college, McKinnon worked for the video game company Ubisoft as a game designer.[1] At Ubisoft, he was a part of the concept team for the tactical shooter Rainbow Six Siege.
In 2012, McKinnon received his first commission from Wizards of the Coast to illustrate a card for the Magic 2013 core set of Magic: The Gathering.[3] He has since provided art for more than 100 Magic: The Gathering cards, having gained a reputation within the Magic community for his wistful, dreamlike compositions.[5][6]
Aside from illustration work, McKinnon started a film production company, Five Knights Productions, with his brother, Ben. In 2013, they released Kin, a short film which went on to win the Best Cinematography awards at both the Montreal Fantasia Film Festival and the Cyprus International Film Festival.[7][1] In 2015, the two McKinnon brothers completed Salvage and Requiem, two more short films set in the same Kin Fables universe.[8][9][10][1] After Ben died in 2016, Seb and his brother Liam started work on Kin Fables: The Stolen Child, a Kin Fables feature film in honor of his brother.[11][4][12] Seb has run two successful Kickstarter projects to fund The Stolen Child, offering playmats featuring his Magic: The Gathering art as compensation.[13][3]
In addition to digital illustration and filmmaking, Seb McKinnon produces music under the name CLANN.[2] Much of the music in the Kin Fables films was made by McKinnon using the Logic Pro software.[1]
