At first, it was difficult to get all the face since the blond hair would mix with the skin and I had to do the eyes, nose and mouth separately. In order to trace the image, I rotated it and used the screen itself with 100% brightness.
Afterwards, I planned the colours so I did not get lost. I looked at several photos of space and supernovas. I could mask it automatically with the black and white blocking. Then I knew I was ready to paint.
Finally I painted light colours first, then the background, and once it was done I mixed Indian Ink, pastel colours, white acrylic paint and white pen. Done!
