Hi!
I'm Vina, and I play Artemis and Calypso as canons. Its nice to meet you Niahi2!
So a few things about your character app.
One, her history is a little confusing. You could elaborate more on the things she saw, maybe how her family were monsters. Did she have a family before, and they were kidnapped? Its all a little confusing XD
Two, her personality also needs to be elaborated. Four sentences is the minimum for personality, so why not give some more traits and such to her?
Fatal Flaw could also be elaborated on, just to tell us how Vanity is fatal for her.
Physical Description needs to be longer, especially if your not using a picture. Four sentences is the minimum here too, so I'd make full sentences for each part of her appearance [Example, eye color, Hair color, Skin color..]
Charmspeak is a forbidden power even for Aphrodite Kids, so I'd remove that.
And her celestial bronze dagger wouldn't really be able to see the past. It sounds a lot like Piper's knife, and her's was pretty much one-of-a-kind.
If you'd like any help, I'd be happy to oblige (: Just shoot me a PM, and I'll do what I can XD
