When forming the image of an angel, I was guided by my idea of them as sophisticated creatures who nevertheless handle weapons perfectly. That is, they should be thin, with slightly elongated limbs, but at the same time have good mobility. Warriors wear light armor that allows them to be quick and agile in combat, and use long swords and spears as weapons. Angels have lightweight bones for flight (like birds). On the head there are something like horns that are connected in a circle (nimbus). They read them sound and electromagnetic waves.
The purpose of the design was to reflect the grace and sophistication of these creatures.
