Kingdom of Knuffel

I'm guessing early 20's here.

Hmm tricky one, you look young yet very mature.
Maybe late twenties.

For a which performing blood magic and domesticating an effing DRAGON? I think you must be at least 500 years old, I mean you had to master those things, right?

Late 20s--young, but no longer naive

You appear to be an immortal spirit so age doesn't matter for you.

You're probably in your late forties, slowly transitioning into the Hollywood wicked witch that they always cast women of that age as.

With all the ribbons, I'm thinking between 8 and 13 years

Probably mid-thirties... the jaded woman at the costume ball trying to steal the prince from a younger woman.

Just 18 years od. You are so young...

I'd say around 17, looks like she's off to prom.
