Egyptian art mainly describes architecture, crafts, literature, music and mainly, was closely linked to religion, so it was fairly standardized, not margins to creativity or personal imagination, because the work should reveal a perfect command of techniques and not the style of the artist.
The biggest difference of the art that we see today is the freedom that the present artists have in representing their art, something that was not common at that time. At that time the artists had to follow the artistic pattern.
