I have finally come to rest on all my character's final designs. Here they are (OCs):
ASIA- Short (shoulder-length) black Hime-cut hair and honey (golden/amber) yellow eyes.
RINJI- Long (waist-length) light teal hair with some hair covering teal-grey eyes.
ALEXIS- Dark red angled-bob cut hair with black streaks and water-blue eyes.
I edited them to make them all special. Asia is a super-smart Harry Potter Ravenclaw witch with a Greengrass curse; Rinji is a super-accomplished yet shy and kick-butt Bleach captain; Alexis is a super-emo and mysterious FNAF:TSE girl.
