NG-PrincessMiAmoreCadenza Or more commonly to her people, Princess Cadence (Cadance?). She rules the Crystal Empire with her husband Shining Armor. She is well loved in the eyes of the crystal ponies and she is always willing to lend an ear to help with their struggles. She, like Twilight, spends a lot of time actually out in the respective places interacting with all their subjects. Princess Celestia and Luna don't often get that luxury as they are quite a bit busier than the other two princesses. Cadence is kind and patient, but don't think just because she is the Princess of love that she can't or won't fight to protect what she cares about.
(I just noticed the princesses all have cute tiny little ears it seems?)
Edit: v2 I honestly hated the I drew her the first time so I'm finally getting around to re-doing her and I'm now much happier with her design :3
