This is a scratch-built Imperial Star Destroyer. It is made of plastic, cardboard and things you can easily find at home - see the last picture. The neck and bridge are based on the paper model.
The main body is made of plastic and reinforced with cardboard braces. After that I glued a layer of sturdy paper, where I engraved the hull pattern, decks, windows etc.
I used beads for the bridge deflector, caps from dishes-cleaner bottle for the main engine thrusts and pill cover for the secondary engine thrusts. The supporting pylons for the bridge deflectors are made of small splinters.
The superstructure is made of plastic or cardboard and a layer of sturdy paper, again with engraved pattern.
I painted the model with the Revell Night Color, so it "lights" for some time at night.
