Order of the Crysto-Equestrian Empire

Oath of the Crysto-Equestian Order
"I, (name), of the Order of the Crysto-Equestian Empire,
truly swear to the throne of Queen Galaxia,
that I will defend the Crystal Heart, the Ponies, and the borders of Equestia
against all enemies, 
and bear true allegiance to our loyal subjects."

So I thought of these three as the original trio who're protectors of the Crystal Heart of the Crysto-Equestrian Empire (from left to right: Luna, Sombra, and Celestia). This is taking place some thousand years ago, before Sombra was crowned King, and before he utilized his power of corruption. And don't take the oath to face value, this was for only for fun. I am taking some approaches to the lighting, and the depth of blur, so please bear with me.
