His approach to printmaking relied on clarity and structural precision. In works like The Waterfall and Tree, he moved away from the whimsical chinoiserie of the previous generation. Instead, he used etching to explore the textures of the natural world and classical mythology. His series of plates shows a disciplined use of line to define form. He often collaborated with other engravers to reproduce complex scenes, such as Hercules and Cacus, where he balanced mythological narrative with a firm grasp of anatomy and light.

Modern collectors value Pillement for his clean, graphic style. His etchings provide a sense of order and historical continuity that fits well in contemporary spaces. The monochromatic nature of his prints allows the viewer to focus on the technical skill of the line work. Pieces like The Love Trap or his botanical studies offer a sophisticated aesthetic that avoids the fussiness of late eighteenth-century art. These works function as quiet, intellectual additions to a gallery wall.
