Eternity by chrisdown
Produced with airbrush, paintbrush, toothbrush, scalpel, sponge, Corel Painter and Photoshop. I think that qualifies it as Mixed Media.
The cross and parts of the background I painted some 15 years ago using a strange process of ground rock and chemical pigments suspended in liquids and applied to a board surface with a variety of methods. Not sure if that will catch on. It was used for the cover of one of my books in 1998. Painting the figure required far less cleaning of brushes. None at all to be precise.
The figure is referenced from the stock of Marcus Ranum on Deviant Art. http://www.ranum.com/
