This Paint Shop Pro image uses Terragen, and tubes by Barry Davies, Hoods and myself. The snowman is adapted from a Poser 4 figure.
This image was painted in Painter 6 impasto, using a Terragen background, Barry Davies's tree tube, and the Poser 4 snowman on layers underneath the painting layers as guides. Only the sky of the Terragen is visible from the originals. The rest have been completely painted over.
