If you want Voyager bridge concepts you´ll love this page: http://www.star-trek-voyager.net/btshtm/bts_bridge1.htm
Those are some interesting concepts. Truth to be told, though, I would never my bridge like that for some reason... The only one remotely interesting is the second one from the bottom. I think it would have been cool to have a bigger tactical console behind the captain, but they're right in that it would look a lot like the Ent-D.
Thanks. It´s one of my favorite sources of inspiration. Make sure to check the other sections as well (e.g., the in-depth look at the design process for the ship´s exterior and the behind the scenes section in general).
Always found bridge designs very interesting to look at, especially "non-canon" one. It's fascinating to see how people see the idea of a center of control, putting in places strange and unusual ideas too.
Actually, that is the USS Sao Paulo, also a sister ship. The USS Valiant has red markings all over it. One can see it on my Flickr page on page 1 of this thread.
