Well, the working process i chose to follow was....
-Get backgrounds cut into 4's
-
Pre-Prepared background
-Choose image to paint
-Blot white
under colour "
silhouette" of image (wait till dried)
-Paint image in with colour (leave to dry)
-With a
Nico, outline image
-Go back over with charcoal/pastel (if so desired)
-Seal work for all mediums

(this is a
silhouette layer)
