Feder's current paintings have evolved from studies of geometry and urban visual choreography toward an edge, as described by Michael Paglia (Westword): "a reconciling of opposites... the tension between representation and abstraction, with the resulting paintings flipping between the two." Simone Kussatz, (ArtScene) writes that Feder’s paintings “are more about color combinations… and how paint is applied than subject matter” and also that the work is “at once an aesthetic expression and a spiritual engagement”. Further describing her work, Corrine Joy Brown wrote (Colorado Expressions): "Through line and shape, color and texture, she renders a new reality so sublime as to leave the viewer spell-bound at its beauty. We sense what is beyond, or far beneath. We stand at the edge of the experience and then, suddenly, are immersed in it." "Her work reveals nothing less than the hidden tensions of contemporary life", writes Peter Illig, referencing buildings and urban architecture that "...stand in for human relationships… the constant contradictions of appearance versus truth."
A third generation Denverite, Sharon studied painting since early childhood. She learned from Colorado Modernists Ed Marecak and Mark Zamantakis, then studied under Michael Spafford, Norman Lundin and Patty Warashina at University of Washington in Seattle, culminating in a prolonged mentorship with Bob Froese in the 1980's. She graduated from Regis University in Denver in 1996.
Her work has been enriched and informed also by decades of technical experience as a set designer, muralist, and sign artist, along with a life richly lived as a mother, mate, and student of nature. Her paintings and murals are included in numerous corporate, private and public collections.
