Martini belonged to the Neoclassical movement, though his skill lay in the translation of large-scale paintings into detailed copperplate engravings. His work often captures the social rituals of the art world. In Exhibition of the Royal Academy, 1787, he includes the spectators as much as the art, showing the fashion and manners of the Georgian era. He achieved a level of clarity that allowed viewers to identify specific paintings hanging on the distant walls of his scenes. This technical precision made his prints popular among those who wanted a record of the great exhibitions.

Modern collectors value Martini for his ability to turn a room into a subject. His prints offer a view into historical interior design and the evolution of taste. Because his works like General View of the City and Port of Catane combine topographical accuracy with fine line work, they suit traditional and contemporary spaces. These engravings act as a link between historical documentation and fine art. They provide a sense of scale and history that works well in a study or a hallway gallery.
