His love for fine detail is something he shared with older French sculptors like François Girardon and Antoine Coysevox. Imbued with the French academic practice of searching for exemplary prototypes, Le Gros looked very closely at all the art around him and found solutions by today less well known sculptors like Melchiorre Cafà and Domenico Guidi but also painters like Giovanni Battista Gaulli helpful, and he adapted them for his own work, often transformed to such a degree that the prototype is hard to pinpoint. There were only very few artists who worked successfully in a similarly playful style as Le Gros in early 18th century Rome, namely Angelo de' Rossi, Bernardino Cametti and Agostino Cornacchini.
Le Gros's artistic style was characterized by a playful approach that drew inspiration from the French academic tradition of seeking exemplary models in art. He studied various pieces around him, adapted these models to his own work, and transformed them into unique creations.
