Kolby Jukes, formerly of BioWare, is now a Senior Character Artist at 343 Studios, where he got to build the 3D models of Halo 4's villain, Didact, in excruciating detail.
While at BioWare he worked on Mass Effect 2 & 3, building the game models for some of the series' biggest characters, and before that, he's worked for clients like id Software, EA, Dark Horse, Gearbox and Warner Bros.
Most of the stuff you'll see is for Halo 4 and Mass Effect, but fans of comic series Invincible will see something extra, and awesome, below.
You can see more of Kolby's stuff at his personal site and blog.
