Sci-fi Space Station
This is a model based of a sci-fi space station. but as you can see its not exactly like the image but, I could not replicate the floating discs on top of the structure.
Here is my insparation.
Main Superstructure Base
Cut out a circle as shown then curve into a slight wide cone.
Add the Under City Parts
Cut out multiple shapes as shown in first image. then glue them to the bottom.
Glue Small Circle on Bottom
Then glue a small circle on the bottom of the space craft.
Mast Details
then add the discs to the mast with small strips of cardboard.
Jet Boosters
make three small rolls of cardboard and glue them on the circle, next add a small satalite on the superstructure.
Done!
now you are done roughen up the underside for detail. and finish.
