Mystagic: I didn't base her on Royal Rose, but I agree that they look similar. Actually I like Rosa Regale. It sounds unique.
Do you know what this means? You should design ponies for Hasbro!
Haha, glad you liked the name. I'm pretty sure no one has ever named a MLP Rosa Regale before! You could also do Rosa Royale, if you don't want the same name as the Rosa Regale wine. Oddly enough, there *is* a pedigreed thoroughbred horse named Rosa Royale--I just Googled the name! It's also a type of pinky-purple bicycle, but I'm more amused by the horse.
