What do you think of the names of my characters?

I really like the names, but to me it seems like you are trying to fit too much into the characters' personalities. Altered personalities: witty, strong-minded, cool, control freak, careless, forgetful, whimsical, intelligent?! This combined with the whole identical twins -> one person -> fraternal twins really makes it seem like you are cramming the characters. Try making other characters, or even another story if you like some of the aspects so much. But as for the names, I think they are really cool! Samara sounds really fierce, and Violet matches her character too, no matter how confusingly complex she is. :) I also really like Samara's personality, but does she have a kind/sensitive/emotional side? I think SHE could have a more complex personality.
