Her technique synthesizes the disciplines of painting, drawing, photography and collage into a cohesive whole. Kaleidoscopic and bordering on the psychedelic, Kejriwal's paintings revel in minutiae, overflow with information, and convey multiple viewpoints simultaneously. As in her earlier works, the artist lavishes her attentions on the surfaces of objects, articulating the differences of materials and replicating the infinite varieties to be found in both the natural and man-made worlds.
