New Character Concepts for ''Friendly Chaos'' Picture

3 designs for characters, and I want opinions before I make real characters out of them. :3

These characters are:

-Amber's big sister, and the one Felix directly serves. Is also a talented violinist.

-Eiji's partner, working with him, under their yet-unknown boss. Very strong and flexible.

-Earlier classmate of Kevin, Trey and Zack, now working as Sylvia's assistant. Like Kevin, she also has abilities related to Norse Mythology.

Shall I keep one, two, or all of these? Tell me what you think.
