Trying a different style. It's based on my old sketch. Just an idea. For fun.
The bodyguard could fight both on foot and on horseback with the spear or use the sidearm - eket in extreme close quarters fights. (inside the palace halls for instance). He also wears karma - Númenorean helmet made of overlapping metal scales covered in leather. His armour and (especially) the helmet would look much more ornate and decorated if he was wearing a parade dress. This equipment is more war-suited.
(and yeah, I know I spelled Númenorean wrong. I'm too lazy to fix it.)
