Excerpt from patreon: (textless versions can be found there as well)

"i came up with a concept of her and i used this artists work as a reference (https://www.pinterest.com/pin/1119355682382740197/ ) for her outfit. but basically this version of her is set in a world where after the latest canon releases of her - Zuko appointed her to become one of the heads of the fire nation education system. So she's an instructor of the fire nation! ima call this version of her "queen azula""

obviously theres more lore behind my concept but thats a brief idea just to set the tone for future animations with this design.
