Altman's "glazed" abstractions serve to complement a structure that emphasizes modern elements, while co-existing with Colorado's natural beauty. The artist's work can be seen as representing elements found in nature, while maintaining a rich elegance. The paintings are resonant with color, ranging from earth tones to primary colors and everything in between. One color and its variations usually dominate a painting. The scratched surfaces add a primitive look that is reminiscent of the way nature wears away at the earth's surface in stone.
