pink hair: Fiona- open person, not afraid to speak her mind. strong willed, and a bit of a goofball. (she usually has her hair down, but I was being fancy with this picture)
green hair: Gwendolyn(Gwen for short) - she's kind of ordinary. A good hearted, honest person, works hard, book smart and quick minded, but really bad at arts/crafts/cooking/creative stuff.
Blue hair: Mason - the shy, misunderstood guy. He loves cooking and baking, and is really thoughtful and kind, but doesn't have many friends because he's somewhat socially awkward.
Brown hair: Chace - the stereotypical school heartthrob- I kinda threw every cliche at him - rich, models, good grades, social, rides a motorcycle, nice/polite, sparkles in every panel. But he's actually frugal because he hates his rich parents and plans on moving out when he turns 18.
They're supposed to be in high school even though they look older in the picture I provided, I was having fun drawing some formal wear but it's the best picture I have of all four and I can never choose who the ask to have drawn XD.
Thanks so much!
