What distinguished the Amarna style from earlier Egyptian art was a sense of realism and immediacy.

The Amarna art refers to a type of art that was used in Egypt during and after the reign of Akhenaten in the 14th century BC. It was sort of revolutionary, and differed greatly than the previous type of art that was generally always used. It showed a bit more realism than the previous eras.
