His work is defined by the strict adherence to classical form and clear, linear compositions favoured by the Davidian school. Alberti focused on mythological subjects and historical narratives, often using a cool palette and balanced arrangements. He avoided the loose brushwork common in earlier Dutch art. Instead, he applied paint with a smooth, polished finish that emphasised the anatomical accuracy of his figures. This method reflected the intellectual demands of the era, prioritising order and historical authenticity over emotional display.

Modern collectors value Alberti for his clean aesthetic and the architectural quality of his compositions. His prints provide a sense of calm and structure that suits contemporary interior design. The historical themes offer a window into the Napoleonic era without the heavy ornamentation of the Baroque period. These works function as sophisticated accents in a home, offering a connection to the scholarly traditions of European art history.
