4 - Here I just paint in the details and add the finishing touches. I mainly use the cover pencil in Painter for painting. It's simple and similar to a digital airbrush but ends up feeling more natural for some reason. I use the digital airbrush too for adding a punch of color where I need it. I keep them all at low opacity to keep them versatile and to maintain the more natural feeling of building the paint up.
|3 - paint basic colors into Color or Colorize layer.|
