Akala Maya
Appearance:
Hair like devil horns because obviously she's a devil
Young lady age 15-20 (even if she's really at least thousands of years old) = makes her look innocent and approachable. She's not supposed to look intimidating femdom maxed like a typical female villain.
Her outfit = while it violates catholic school standards (skirt has to be to your knees while sitting down), didn't really design her to be pure sex appeal as that's not her style. Her char design could be either a protagonist or antagonist.
Color scheme = black because she's obviously evil. Little bit of red because red is the color of blood. And she's bloodthirsty being a devil and all that..
Personality = sarcastic, smiley, dark humor, very good at masking her bloodthirsty nature.
Claudita
Appearance:
When I designed her I had in mind the good girl look without looking like a damsel in distress. Straight long hair seems to be standard for female protagonist.
Outfit = modesty and functionality in mind.
Color scheme = pink because it's a traditional feminine color. Red is also associated with being "fiery" as it balances out femininity. She is a very capable fighter.
Personality = numb stoic with a little bit of smile and bubbliness. Imagine Rei Ayanami with a little more emotion.
