These strokes done in gold, white and pale sienna will be repeated in layers and glazes over quite a few days with lettering and other imagery in between and there will be color washes throughout. They are abstracted to convey the feeling of movement. Later there will be various shades of gold powders mixed and applied in glazes as well. The final result should have the feelings of movement, fire, power, majesty, etc. The image of the angel will then be painted over this ground.
There is not much to decipher of this wrinkly canvas at this stage. Because the canvas isn't on a frame or stretcher bars, it will go through various stages of buckling as the paint dries unevenly. It will eventually become flat again as the whole surface is covered. This is all part of the process... I am not looking at what is on the canvas today, I am looking at what will be there in 2 weeks. The most important aspect now is to establish that feeling of movement and power.
