It's magic, indeed.
When I paint I do in very relaxed after a meditation about someone or something,then I keep nothing in my mind, no idea, no goal, only focusing on my senses. The pencil's touches and the colors are done eyes closed . I have tricks to help me to shut out my mind in the first step of the watercolors . So it's always a surprise for me. Then I search with my computer the more meaningful versions and details.
