Is this character Mary Sue?

Question

Vinca “Vin” Hughes

~Personality~

Out of the four females introduced at the beginning, Vinca is the third oldest as eighteen. She has high standards and expects perfect from those she associates with as well as herself, this leading to her lack of confidence. She is very insecure, awkward, sensitive, and hot-tempered— the latter when things don’t go her way. Vinca can be very sweet, but on other occasions can be ruthless and amoral to get her way. She has a competitive personality and will accept a challenge that comes her way, no matter how high the stakes. Vinca often feels inferior to Lilyana’s mature beauty and feminine pursuits and just about everyone else when it comes to swimming and cooking; both of which she cannot do. She tries hard to excel at things but is clumsy and almost completely inept at almost everything not involving her magical ability to manipulate shadows, schoolwork, or things where she can put her devious mind to work.

You seem to have put a whole lot into her, which does make me think she could be Mary Sue-like.  If you prefer her over your other characters, that could be true as well.
