Okay, the next part of this is not a kit, but the scratch build of the display base for the whole diorama.
I chose to make it roughly 10" x 10" x 10" to conserve space but still provide decent room for detail.
The frame is made up of 3/16" black foam core cut into panels. I used craft glue and painter's tape to stabilize it while the glue dried.
Testing to see if the size will be good. Orginally, I was going to have the back wall continue upward for the actual facility detail to show. But cut that out, as I didn't have the material to extend the back wall, plus the Zeong head coming up over the top will hopefully prove more dynamic.
The next step involved crumpling newspapers and ads to start the base for the rocky structure the Gundam will be standing in. This will be covered with plaster cloth to create the rocks, themselves.
With that done, I used basic acrylic artist paints (not craft paints) to finalize the detail and give depth to the terrain. I decided to add an extension to the bottom using the little bit of foamecore left over.
That's it for this part, but more will come into work on the base, as it will have some more work to hold the models themselves.
