Another Excelsior-class ship that you might try doing (this is NOT a request, BTW) is the Lakota bridge, from that ship seen in the DS9 episode "Paradise Lost." You see a little bit of it in the episode behind Captain Benteen: the original set is a redress of the Defiant bridge with a few displays taken from DS9's infirmary. The Lakota had completed a refit and those console/displays could be temporary. As with the rest of the bridge, you take that oft-redressed bridge and change the parameter stations to be more Defiant esque with the Defiant-style buttresses. As with the center seat and Conn/Ops...you decide.
You know, you might want to try going with the transporter pattern used on the Yosemite's transporter booth seen in the TNG episode "Realm of Fear," the inverted one.
@Rekkert - Don't forget the Excelsior helm and nav have that little extra thing with the support and console as seen here: movies.trekcore.com/gallery/displayimage.php?pid=52620&fullsize=1. Also, keep in mind that they DO have some clickety-click physical push buttons!
Interesting. Is that big curved console a tactical / security console? And for that matter, are the two side ones for first officer and mission specialist?
Seanr had a theory that the Enterprise-C bridge seen in "Yesterday's Enterprise" was a secondary bridge, like a battle bridge or auxiliary control room.
@richiewilch - the Equinox's engineering was only one deck tall at least from what we saw of it in the Voyager two-parter. The same might be said about the Pegasus from TNG's "The Pegasus."
@Rekkert - I don't like it either. I actually dreaded the idea that they'd use it for the Enterprise-E after they trashed the Enterprise-D in Generations, since the design appeared in a DC Comics TNG story in 1994. John Eaves's Sovereign-class work of art is FAR, FAR better (and indeed better than the other concepts)! If I'd use it in one of my stories, it would be a ship I'd likely trash. But I've dubbed the ship class the Piper-class.
