Solar Flare/ Blazing Corona

i've seen very common interpretations but i never liked the armour, or how her cutie marked was changed. When Luna was NightMare Moon her cutie mark changed color so i did something similar. Because Celestia is the princess of the sun it makes sense to turn her mane into fire that could burn ponies alive. I also imagine SolarFlare having massive nuclear powers like the sun. As for the armour i felt that she needed armour thats more like her, metal spikes are nice but the sun is a circle, and has swirling sheets of fie coming off it. I felt that it needed to not be so spikey.
Plus fire shaped magic... I messed up with it and i want to give it a smoother more magical fire look.
