just make sure its not the SAME mesh
also STO's models are pretty low quality...
This. You've shown you can do some neat touch-ups, I'm not really familiar with any of your other work though, unfortunately. The guys are right, as by comparison STO's models are much more poly savvy, despite the LOD's (And from what I have seen the "modular" -- I guess you'd call 'em -- sections aren't unified even to themselves) but they're for the most part still pretty. Using the Yacht from the game as a reference point ought to make for a beautiful mesh with a slightly more... What's the word I'm looking for...?
Distinct look. It's true, though, a flashy yacht for screenshots and such would be very cool.

Best of luck to you in your efforts.
