Terran Protectorate Bridge

This is an example of a typical Terran Protectorate Bridge layout. This one is specifically a Stalwart Heavy Cruiser during the first Great War between the Terran Protectorate and the Imperial Consortium. While the Stalwarts are now the main law enforcement vessel for the Guardsmen Interstellar Security Service, they started out as the ship-of-the-line for the Protectorate decades ago.

I take from a lot of different inspirations for the design look of these. Obviously, there's the classic Star Trek influence with the command chair, but I use far more military colors and design aspects, make the stations separate, give it a more kinetic feeling helm, so that there's more a feeling of the vessel being piloted, esp. in combat and during heavy maneuvering. The pilot is even wearing riding style gloves to relay the feeling he's about to do some serious flying.
The sensor board which is just off screen, but you can see the guy looking up at it, is very anime-inspired. It's one of those big wall "threat boards." Tactical is actually kind of a gunnery chair, like you'd see in some kind of high-tech turret, but placed on the bridge, again giving the bridge space a more "kinetic" feel when the action starts. Also, because fighters play a big role in this, and I like the "conversation" area it creates, there's a big map table in the back of the room, behind the XO, who's standing next to the captain. That was inspired by countless submarine dramas and Battlestar Galactica. It allows characters to huddle around this upward lightsource that gives their faces a dramatic effect when making plans to take on dire and nigh-impossible objectives. 
I try to strike a balance between function, visual cues (most people immediately recognize that guy in the chair as captain of a sci-fi ship without having to be told) and things that complement story telling elements.
