I couldn't wait working on the general of my Impetus army, Robert Baratheon, Lord of the Stormlands, known as "The Usurper". Base-model is the "Count of Vendome" of the Perry Agincourt range. I sanded off all the heraldry, resculpted the livery and added his famous warhammer and antlers.
I'm still uncertain about the antlers. These are just taken from a 5th Edition Bretonnian knight and don't have the "aggressive" look I aimed at.
