I
paint these maps on 300 lb. paper, using Holbein and Windsor-Newton watercolours.
The source data is compiled from satellite images and existing topographic
maps.
The maps are meant to be geographically precise, but they are first
and foremost works of art, so I may take liberties with leaving out
roads and towns.
If
I can visit the area, the the landscape colouring will be based on my
personal observations of the earth tones and vegetation.
