I vectored my OCs Gender bend. Help naming it?

[Guardian Braveheart 23]

My net was out yesterday, so I sketched this in my sketchbook. And since I had plenty of time, I vectored it on Adobe Illustrator. Is it good? It's a gender bend of My Ponysona. I need to name her, any Ideas?

The head needs to be a bit more curved. The chin is to flat. It's a great try though. 

 

For names

 

1. StarShield

2. Guardian

B... but the male is already Guardian... Maybe StarShield though, that would be nice. Thanks for the feedback.
