For Leiva, his art does not exist in just one world. Instead, it is a labyrinth of opulent structures, patterns, and ornaments. This is especially true for his Barcas series, in which Leiva incorporates figures reminiscent of sea creatures and presents them, his protagonists, as spheres, spikes, and surrealist characters. Combining organic filaments and form with geometric intricacies is prevalent in the details of Barca V, where winding tendrils doused in rich color are incorporated in a free form that culminates in a spherical top. Leiva plays with dimensional qualities, manifesting shapes sculpted and painted in the glaze.
