Painting on the gold leaf for this picture has not been a success. First mistake was not having the canvas vertical when painting. The gold reflects the light back most beautifully through the paint but I painted the canvas at a 45 degree angle so when I straighten it ... whoops ... a mess. Second mistake was not thinking about paint transparency/opacity. I should have constructed the inside using transparent colours allowing the glow to show through the paint and used opacity for the outside allowing the gold to be unpainted.
So I have quit on this painting and will retry later.
