Nice model! Very credible. I see so many spacecraft models that make no sense physically or aerodynamically. Guess i'll also modify a default Vue material for the ship i'm building in Silo 3D for the Earth scene. Most of the sub objects making up the ship will be texture mapped in Adobe Phosotshop with unwrapped UV images, like parts of your model - but will still need 1 or 2 regular materials as well.
