Original Description:
 
All Those Lives Through the Looking Glass  
This is somewhat a silly drawing. I was thinking to label this as an AU drawing, but it’s not fully connected to it so I didn’t in the end. Tho the headcanon this is connected to IS part of my AU.
 
The headcanon is that there are multiple mirror portals that lead to different alternative words and timelines. They are not always a mirror; it just have to be a reflective surface that gain magical abilities somehow (this is how I brought Potion Nova into my AU, because in her case the portal was the lake, she used for potion making). So there are, for example, multiple different Twilights. Based on the spin off shows, new generations and my AUs for this drawing.
 

 
From the bottom to the top represented (with explanation, if needed):
 
Twilight from my AU, ‘My Little Pony: Years Later’  
The original premise for my AU was that, as the name suggest, it takes place years later. It was created before season nine (and of course the episode, ‘The Last Problem’), so the new story is, it takes years later in an alternative timeline where Twilight stayed being the Princess of Friendship, and didn’t become the new ruler of Equestria (theres other differences, but that’s the main one). Honestly, I wouldn’t mind renaming my AU Friendshipverse, but I’ve been using the MLP:YL label so long, it’s kinda too late for that.
 
Twilight from ‘Pony Life’
 
Twilight from the canon timeline of the show
 
Twilight from ‘My Little Pony: A New Generation’  
While it seems like the movie (and the future series) is in the same universe as the show, if feels like for me, it may take place in an alternative timeline. For me, this explains why Windigos didn’t come when the fallout between the ponies happened, why there are no other creatures, ect. This can be disproven by the future show (and probably will be), but this is my headcanon for now.  
So this version of Twilight is drawn in the same design as I do the characters from Gen5.
 
Twilight from Equestria Girls
 
Twilight from my AU, currently named ‘Humanized Equestria’  
Not a clever name and definitely will change, but when I frequently drew humanized pony designs, I was thinking about making it into an actual AU. And thinking bringing it back, so I can use it to practice drawing humans (and have some fun with it).
