Nice shuttle Jeff. And yeah, it does look sorta Nostromo or rather "Leviathan" shaped from the "Book of Alien" pre- production art. Which is cool!
(oh and yes, we model and texture in LW. Use Photoshop for maps)
As for who Dave is and his model, I know nothing about. Koji wholly built the Defiant we used. Nacelles Lighting and certain textures tweeks by me. It was done at EdenFX with reference help from Doug Drexler from the Art Dept and by extension whomever gave him reference. That's it.
