MLP AU : Twilight the dark witch

so I wanted to take a little break before working on a commission of celestia
Twilight's AU design is the only one without some form of armour so far
in this AU she's actually a dark magic user.

I have her story done but I need to think of details
If I can i'll do a comic ^~^'''
btw she used a curse she has markings and her tears are red  0v0
Other in the AU series
