Armstrong’s work can be described as narrative realism with a nod toward impressionism. Specializing in oil paint, she has primarily taken commissions, but her work has evolved over time to become more narrative.  To this she states, “I’m seeking to express through my current work, the psychological and spiritual aspects of human nature. I believe that art has the ability to help us understand ourselves better and find that becomes increasingly important as life continues to change globally and personally for us.” 

Because of this focus, much of Armstrong’s work in the last several years is conceptual or thematic. Part of her process is to discover and convey the emotional and evocative qualities relating to story or personal life experiences that have universal concepts. Often she utilizes symbolism in the works themselves or in the titles to express these qualities. She is heavily influenced by historical masters of the late 1800’s Naturalist movement and the figurative tradition of the nineteenth century European art academies.

Armstrong attributes her endeavor to becoming an artist to a few notable individuals. Her earliest art as a young girl consisted of drawings that she would mail long distance to her artist grandmother, Mildred Marchi,  to critique. She began a serious study of art after taking a head drawing class from artist Leon Parson at Ricks College (BYU ID, Rexburg, Idaho), who encouraged her to change her major from psychology to art. At Brigham Young University in Provo, Utah, Armstrong studied under James C. Christensen and Wulf Barsch, who influenced her artistic vision toward more spiritual subject matter. In the years since earning her Bachelor of Fine Art degree from the San Francisco School of Art, Armstrong received instruction and mentorship from several renowned artists; most notably, artist Daniel Sprick. 

Armstrong currently works and resides in Colorado. She is represented by The Main Street Gallery in Carbondale, Colorado.
