A look at the design elements:
Linking elements are colours, fur and egyptian features like nemes- headpiece with horizontal stripes or bands of hieroglyphs (copied original texts from the book of the dead, random combinations somehow don´t look “right”). Also both gentlemen are over 1,9 metres tall and have the same sense of humor.
Differences are the implied mythological elements: The Scarabaeus armour on the left consists of round shapes and emblems. Scarabaeus is a symbol of life (at this point I´m tempted to quote Pratchett, but instead of that a recommendation: “Pyramids”- or better: all he wrote. Try it.).
The model for the armour on the right is the mythological monster Ammut: a mixture of lion, hippopotamus and crocodile (in other words: everything that had a big mouth in egypt). It eats the souls of the dead who fail the test of the scales...
The Ammut armour on the right shows lion´s mane, hippo´s tusks and crocodile´s teeth. It is dominated by spiky forms.
The styles symbolize the Pharaoh´s power over life and death and are also reflected in the shapes of the warlord: as Amuthep (scarabaeus) or Bahat al`ask`r (the wide-open maw)- which can change very rapidly according to his master´s whims...
You don´t have to overload your creatures that way but it enriches the ambiente of the game (scholars can point out particulars to their warriors which will doubtlessly encourage them to no end) but in this case the details are just bycatch of what the figures should look like.
