Before to paint the hair of the three babes, I've worked on the base.
I've airbrushed acrylics: white, red and black (from Tamiya); the gold paint is AK True Metal Gold.
Then I've used AK aequous pencils (black, dark grey and white) to simulate marble Looks also a little bit like granite; but anyway I really like the result!
And then first airbrushing of gloss varnish - at least one another airbrushing of gloss varnish will be needed to have a "brilliant" effect.
