I finally got some detail work done on the nacelle pylons:
The pylons aren't finished yet; there are some additional grills and vents and such yet to add. Ditto for the warp rudders and RCS thrusters, though all of them are much further along than in the previous renderings.
I'm sure you've also noticed that the hull textures are missing. I decided to remove them for two reasons: First, keeping the UV mapping updated with every geometry change was becoming tedious; and second, I don't want to steal my own thunder when it comes time for the big reveal of this model in its finished form, so I'm going to start holding back on the photorealistic WIP images so the end result will, hopefull, still knock everyone's socks off and not just be more of the same.
