Her approach combined Neoclassical structures with a soft, humanising touch. In works like Adoration of the Infant Christ by Mary and Joseph, she balanced religious iconography with emotional clarity. She avoided heavy ornamentation. Instead, she used clean lines and balanced compositions to direct the viewer. This clarity is evident in her Semiramis at her Toilet, Receiving the Message of the Revolt, where the drama is conveyed through posture and expression.

Modern collectors value Piotti-Pirola for the graphic quality of her prints. Her work offers a window into the aesthetic preferences of the Kingdom of Italy. The monochrome nature of her engravings fits well in contemporary interiors that favour clean palettes. Her depictions of historical women and religious scenes provide a sense of calm. These prints function as both historical documents and sophisticated decor for the home.
