This overview of Treetown from Dinotopia: A Land Apart from Time (1992) is drawn using a fairly unusual technique.
I drew a fairly comprehensive pencil drawing on a smooth-finish heavyweight illustration board. Then I sealed the drawing with workable fixative and then with a thin layer of acrylic matte medium.
Over that, I scrubbed on a very thin layer of oil paint (yellow ochre, burnt sienna, and ultramarine blue) thinned with solvent. The more detailed and comprehensive the drawing, the less rendering or modeling is needed with the paint. All I needed were some big gradations and light overall tones. I didn't want the paint to compete with the line work.
