His artistic approach relied on the use of dense hatching and varied line weights to build form. In pieces such as Zittende bedelaar, handen warmend bij een komfoor, he captured the physical reality of his subjects through careful observation. Novelli focused on the play of light across surfaces, a technique he applied to both religious subjects and secular portraits. His work on the Descent from the Cross demonstrates his skill in managing multiple figures within a compact, tonally balanced composition.

Collectors today are drawn to the tactile quality and historical weight of Novelli's prints. These works bring a classical sensibility to modern interiors without the need for large-scale canvases. His etchings, like the Portret van Domenichino, function as quiet studies of human character and artistic tradition. They provide a sophisticated aesthetic for those who appreciate the precision of traditional printmaking. Each piece carries the technical rigour of the Venetian school.
