I was never a fan of how she ended up just looking like a Celestia recolour. Plus, I didn’t like the idea of her being taller than not only Cadence, who’s at least close to Shining Armor’s age, but also Luna, who’s several thousands of years old!!! So that’s why I used a Cadence base, since I think it makes more sense for Twilight to be her height during The Last Problem.
