I downloaded it and went through it. That is probably the most impressive Minecraft Star Trek model there is, and heck the most impressive Star Trek model in video games, full stop.
Never has any game model of a Starfleet ship conveyed the mass and size of a starship. Even the TV shows and movies can't really do that (understandably, due to time and budget reasons). I finally got the sense that these were behemoths housing hundreds of people.
Truly, truly impressive model!
