Brick building

I bought a big piece of cardboard foam and I cut the walls and levels. I glued them all together and fixed them with pins.

I sprayed it with grey primer.

I gave the building a coat of orange.

I painted the rails with metallic paint and I gave the building another coat of orange.

Next I started to draw the bricks and made some bolts on the rails with silver but they are not visible in the photo.
