Thanks for the comments
As for the wood, the turbolift area (as other larger wooden surfaces there) are not a single piece, but are made of smaller pieces, as on the screenshot with the viewscreen. It's just when you're farther away it gives an impression of being like this.
Originally I was doing an Ambassador bridge - now, we have Mr.Probert's Ambassador concept available, so I thought this may go well with it. As the name of the class says it's supposed to be a noble, elegant ship of diplomacy; fitting an admiral or commodore, hence the wood, even if it was not as extensively used in the series. (ST3 featured some Starfleet longue, or whatever it was, it had a looot of wood).
Anyway, for those who dislike wood in such quantity, a different version then ;)
PS: @Lurok -> thanks in advance, do take your time, I'm not in a hurry. Oh, and just went thru your thread - can't see anything wrong with pics there, good presentations and I don't see any visual difference. Maybe it's the subjectivity or modesty rather than pc-specs? ;)
