Your phone/tablet camera can expose what you cannot see! When you think you might be finished with the painting, hold the camera close--real close-- to the painting and slowly move it around. Zoom in. The camera's eye might show you spots that you cannot catch with the human eye.
In the photo below, I didn't see any of these flaws on the painting surface. But click on the image and notice . . .
tiny white spots on forehead and under eye
what IS that pattern looking space on her cheek?
an errant spot of purple on her chin
extra and unwanted build up of pastel on her neck where a stroke stopped or started.
Give it a try, both by looking through the camera and by taking a photo and zooming in. You will see things to fix as well as those annoying white specks of paper showing through.
