His work functions as a visual record of life at Versailles. Cochin produced detailed drawings of court ceremonies, such as the Funeral for Marie-Thérèse of Spain. He captured the social games of the aristocracy in pieces like The Game of Blind Man's Bluff and The Romancer. His technique relied on clear lines and a focus on social interaction. He often depicted figures in relaxed poses, as seen in his Half-length Portrait of a Seated Woman.

These prints appeal to modern collectors who appreciate historical accuracy. His work provides a window into the formal structures of 18th-century France. The compositions are balanced and avoid the excess of the earlier Rococo period. His drawings, such as Le Bosquet de Bacchus, offer a sophisticated look for contemporary interiors. They provide a sense of history through a lens of intellectual observation.
