Original Description:

That mane was a PAIN. Not to colour, oh no, that was easy, but picking the RIGHT colours was awful. I tried like 5 different colour combinations including her original mane colours before settling on the colours you see above, which are actually her original mane colours with the green switched for orange and with a light purple overlay.

Changes made and why I made them:
-Her normal regalia is gone, replaced by gold chains with hanging jewels, mostly because I’ve never managed to get Celestia’s regalia to look right in my style.
-Her base colour is yellow hued rather than pink hued, and she has orange tint to her wings, because I thought it looked nice.
-Her eyes are now pink rather than pink-purple.
-Her mane’s green stripe has been replaced with orange because I couldn’t make her original mane colours look nice here, and I wanted to give her more ‘sun’ look.
-She has pink cloven hooves with long feathering as tribute to traditional unicorns.
-Her crown is now styled to be like a sun’s corona.
-Her cutie mark is a slightly less stylized sun… because I was getting really tired and losing inspiration.
