This is my low-polygon model of the Executor class Super Stardestroyer from Star Wars. It isn't finished yet, but the upper side is largely complete. The model is around 7k polygons in it's present state, i plan it to be around 10-12k when finished. Underside has only the base structure done, will receive detail.
The model is meant to be able for in-game use, but on full-ship renders it should hold up pretty well too.
