Answer:
The answer is perspective.
Step-by-step explanation:
The attention to details, such as the garments rendering, shows the acquisition by the Florentine artist of the influences from the flemish school.
This school moved beyond the flat perspective and outline figuration of earlier painting in favour fo three-dimensional pictorial spaces. The position of viewers and how they might relate to the scene became relevant for the first time. Advancements in technique allowed far richer, more luminous ad closely detailed representations of people, landscapes, interiors and objects.
