The next step is to paint the cave.
It was painted the whole in diluted flat black first, and then cover the white of the plaster.
I finely painted XF-52 Flat Earth, XF-53 Neutral Gray, XF-63 Red Brown etc. with a brush over it.
I recoated the color further finely.
Then, I painted a thin matte black in the entire base using the airbrush.
Painting is finished, I will make a underground water vein.
