The work of Firma Feuchère is defined by a balance of classical discipline and Romantic energy. He trained under Jean-Pierre Cortot and Étienne-Jules Ramey. This education taught him the value of anatomical accuracy. However, Feuchère often chose subjects with high emotional stakes. His designs for decorative objects and sculptures use bold silhouettes. He avoided unnecessary ornamentation to focus on the physical presence of his subjects.

Modern collectors value Feuchère for his ability to translate three-dimensional weight into two-dimensional prints and drawings. His sketches for sculptures possess a clarity that works well in contemporary spaces. The monochromatic quality of his graphic work allows for easy placement in various rooms. His art offers a sense of historical continuity without feeling dated or overly ornate.
