Diners’ work is characterized by its narrative depth and meticulous attention to detail, often exploring themes of human and mythical existence. His sculptures range from colorful wax figures created in the 1990s to miniature bronzes and photographs in the 2000s, showcasing his versatility across media. A hallmark of his style was his ability to develop small forms with infinite detail, as noted by curator Inga Šteimane, who organized his first solo exhibition in Latvia, Cilvēkzvēru noslēpumainā dzīve (The Mysterious Life of Human Beasts), in 1998. Šteimane praised his capacity to maintain a storytelling quality within minimalistic yet highly detailed forms, a trait that set him apart in the field of sculpture. His early exposure to the art world came through a solo exhibition at the Zilberhorn Art Salon in Bonn, Germany, where his wax sculptures garnered significant attention. Over the years, Diners expanded his practice to include large-scale installations, such as an epic work addressing themes of war, and collaborative projects with his mother, Lilija Dinere, illustrating ancient literary monuments. His beach exhibitions in Jūrmala became a signature contribution, transforming the coastal landscape into a gallery space and engaging the public with art in an accessible, open-air setting. As an art historian, Diners brought a scholarly perspective to his practice, enriching his work with cultural and historical references. His exhibitions often incorporated multimedia elements, such as video chronicles, to provide context and deepen the viewer’s experience, as seen in the Pasaule manos sapņos exhibition.
