I had to redo Twilight's face at least three times, because she had "Filly-Face", and while not bad, just wasn't what I was going for.
Why are they fighting? I will leave that up to you.
For those who don't know: Hasbro originally released (is releasing?) this castle/marriage play set with the white unicorn in the picture named Shining Armor, whom has recently been named as Twilight Sparkle's brother in the upcoming season 2 two part finale.
