This was a commission of 4 large (4"x"4) stretched canvas maps that showed the Earth in western and eastern hemispheres, and the celestial map of north and south views. 

Progress shots above show various stages of line art and paint. Some metallic paints were used to create shine.

The above photo is the Argo, a southern hemisphere constellation before I added any color. In more closeups below, you can see how I created a 3-dimensional effect on the snowy areas by using paint thickener. The dog constellation was re-imagined as a Rottweiler as that was the type of dog that the commissioner of these maps had once owned.
