His work is marked by a poetic sensibility, influenced in particular by the Symbolist poets, but also by a strong admiration for his master Auguste Morisot. In his early works, the bluish foliage reveals Morisot's influence, combined with the plastic power and nervousness of gesture that characterize his style. His painting combines strength of line and lyricism, with a lively, nervous touch that enlivens his compositions.
Combet-Descombes also excels as a decorator. He works on decorative projects for public buildings, notably the town hall in the 7th arrondissement of Paris, and in the theater field. His vocation as a decorator seems almost predestined, given his talent for staging spaces with great aesthetic sensitivity.
A recurring theme in his work is the female body, which he celebrates with sensuality. Influenced by Baudelaire, he depicts the female body with a muscular stroke, often executed in a single movement, and often seen high up on a stepladder. With this approach, he transforms the body into a plastic sign of rare sensuality, rendering it both powerful and delicate, in an elegant, sensual dynamic.
In 1925, his work was shown in a group exhibition at the Musée des Arts Décoratifs in Paris, marking the national recognition of his talent. His works, rich in symbolism and emotion, bear witness to his essential role in the development of decorative and landscape art in Lyon and beyond.
