I did this as a contest entry for Scale Model Addict's (SMA) Big Spring Contest 2012 and won second place in the sci-fi category!
Base kit is Ertl's 1/4222 Star Destroyer
Add-ons:
AMP's bridge & spine
Hacker's Venator engine nozzles
home-made decal scribing guide
home-made deflector dome replacements (soon to be a product release!)
TONS of fiber optics & LEDs & greeblies
I practically rebuilt the kit by sanding off all raised details, rebuilding the super structure side wall details, building the trenches from scratch, yada yada yada.
