We printed the robot on a 3D printer. The blank was painted manually. We added scratches with a thin brush and used Vallejo's metallic paint, so that it looks just like a metallic surface.
The froth around the robot's legs was made with foamed putty. With the help of Water Effect, we added water disturbances in the form of little splashes. You can use the same effect in dioramas with waterfalls and icicles.
