this is a nice twilight design. cutie mark could use some work but maybe an Eclipse would look well with these colors.

if the show went on under Faust oh how I wish there was a cross-dimension episode akin to Star Trek's "Mirror Mirror" but maybe less.. bad guy universe kek more-so.. different.. Perhaps Celestia is the younger sister. things like that. The glimmer episode was nice but a few events changing is one thing compared to a greater change like Twilight Twinkle herself existing instead of Twilight Sparkle
