Each line becomes a closed shape I redraw with the mouse and that is given a color chosen by me. I start with the background images and put it on a layer, working in Adobe Illustrator. The thought process is comparable to silkscreen with layers of opaque colored shapes but with the flexibility of the computer to make adjustments along the way.
After the background pencil lines are outlined, then I outline all the shapes of the rock and waterfall, followed by the hill in the foreground. You can see each layer with color and how the drawing looks as black outlines. The computer is just a tool that you tell what to do, it doesn't make any artistic decisions. I used to be an airbrush artist doing this same style and trying to remix colors to match was a nightmare, let alone making changes and having to repaint areas. Sometimes I use colors from previous illustrations like the water color here is the same as the water color I used in the Stone Arch Bridge illustration.
I hope this clarifies the artistic process in creating my illustrations from pencil to final art.
