First I really like how you flesh out your characters: their personality and how they interact in their universe is realistic in a way that they have pretty unique traits while having traits you could easily find IRL.

The fact that she's extremely competitive and determined to success is a strong quality: she wouldn't give up on her tasks or challenges. In the meantime this could be her main default: jumping into lose-lose situations because of how spontaneous she is, and this is definitely a great way to deal with this kind of traits while making a character. You really put a lot of effort into her.

Her design, while being rather simple works very well: not overloaded, not plain, just the small details that make her stand out. I love her fiery red hair too.
