space opera: Imperium Trooper
This guy stands about 8 feet tall, and is mostly mechanical. Red is the signature color for the Galactic Imperium; for basic grunts like this guy, red will be a major element in the design. For higher ups like Uvei Mortis, red will play a much more subtle role in the visual design. For scientists and middle management types like Fentonov, the red will be more of a 50-50 design element.
Oh yeah, and this is obviously a revised/refined version of the sketch I posted of this guy a while back.
