Also, as Rat Boy pointed out in the thread in the Holodeck forum, there are "inaccuracies" to the CGI ship in the upcoming two-parter episode. After some thought today (when I got off working), I wouldn't really say they're as much inaccurate as it is small differences as it is with some ships of the same class of Starship, like the Constellation for example (from "The Doomsday Machine" [TOS]). So, like the Constellation, the Defiant has some differences that make it unique from most other class of Starships while not being too different to be another class of Starship. As he explained, there might be sharper curves on the saucer when compared to the U.S.S. Enterprise, and the Defiant's saucer is a little thicker, which explains how the registry looks like it was "slipping off", even though it's neatly stuck on.
What you did so far is nice, Atheorhaven. Although I prefer the 6 over the 8, I still think it's a nice job.
