Marshall's work is bold, colorful, full of texture and shadowns that gives a three-dimensional quality to the canvases. For her, painting is a meditative practice; an outlet to release intuitive energy and let go of preconceived notions and self-imposed rules or judgements of how she interprets and portrays the wold both internally and externally. Marshall's work or "practice" is restorative, as she creates what she calls "Inward Landscapes".
