This dog-head soldier, affectionately known as Brother Peter was a former lay brothers (who take simple vows and are expected to perform manual labor for the monastic community) all of the brother signed the deeds of surrender when the abbeys were closed. Peter committed to manual work and insistence on self-sufficiency, he took the vow of celibacy, dressed similarly to peasants, landsknecht kit is a stark difference to what he used to wear so i think something with less gaudy colour is more well suited. He's describe as "a creature with unusual stature and frame—being tall, lean, having well-proportioned limbs except for his large head" - by a so called private historian "The crown of his head is bare, the brow exposed and furrowed, while from behind and about the sides falls a mane of coarse hair, black as the forest’s depth—more beast than man. His appearance was remarkably unattractive and his face bore a constant air of impassive, especially when speaking; his eyes were small and grey, his mouth wide, his teeth are sharp with standing prominent."
