It was actually described as a smaller version of the Soverign(Enterprise's) Bridge in Taking Wing.
But As I said this was just my vision of the bridge, but this not the official design.
Well, none of its "offical". Its like being handed a million dollars and being told you can't ever spend it. If anything, you might be able to say it is less non canon then any drawing any of us make.
But thats splitting hairs. My point is that, if thats your version of the bridge, then I'll take it as though that 'is' the bridge. It is just too grey, too confused, and way too many styles going on. I do like that there is alot of homages in it to known bridges, but my taste buds dislike the end result.
