Brad Shortt is a Senior Character Artist at 343 Industries, the (current) developers of the Halo series. For Halo 5, Brad got to play around with Nathan Fillion's (slightly improved) video game face. A lot.
And everyone else's face too, mind. But they're not quite as interesting as seeing the Firefly star look like he's trying to take a dump/is a circus clown/make weird kissy faces.
You can see more of Brad's work at his ArtStation page.
