His artistic method is built upon a constant dialogue between the "pole of culture"—expressed through geometric precision and engineering calculation—and the "pole of nature," manifested in biomorphic rhythms and the dynamics of growth.

The sculptor’s engagement with his materials holds a central place in his practice. Moving from the massive volumes of iron and lead to his current constructions in stainless steel, Yesa has learned to strip metal of its inherent rigidity. By utilizing steel sheets with varying degrees of polish and the specific moiré effect, he integrates light and reflection directly into the structure of the piece, transforming the sculpture into a living, vibrating object. A hallmark of his style is the use of thin metal rods that create a kind of "aerial drawing" around the central volume. These lines do not merely define a contour; they shape an inhabitable space, inviting the viewer into a state of mental co-creation.

Antonio Yesa’s critical acclaim is supported by numerous solo exhibitions, most notably a major showcase at the Centro de Arte Contemporáneo de Málaga (CAC Málaga), as well as his active participation in international art fairs. His monumental public works have become integral parts of the urban landscape in many Andalusian cities, turning the squares of Benalmádena and Alhaurín de la Torre into open-air galleries. Inheriting the traditions of masters such as Jorge Oteiza and Julio González, Yesa creates a unique visual language where the classical understanding of balance and the "golden ratio" meets contemporary explorations of expanded space and modern aesthetics.
