Yeah. I'd love to stay with the original, but I sat and looked at all the females.
Mattie: Long hair, reaches to about her butt. Otome: In twintails, but when down, it's past her shoulders. Rain: Tied in a "brush" at the back, when down reaches a bit past her shoulders (less than Otome). Pyre: Medium-long hair, reaches middle of her back/shoulder blades. Nenoko: Ponytail kept in place with chopsticks, medium-long when down, same as Pyre. Sepia: Tied in back-bottom like Rain, but more free. Little less than Rain, so shoulder length. Wendy: Longest hair of them all. Tied in two tails at the bottom, but when at full length, reaches thighs or possibly back of her knees. Ashley: Curly and puffy hair, same length as Mattie. Claire: Kept natural but tied about halfway. When down, is inbetween Nenoko and Mattie in length.
So in a nutshell, all the girls have long-ish hair. And I feel that hurts all of them as a whole, so I feel Claire could work best as a short hair. Sepia too eventually, but I'm holding off on that since want her to sorta look different than Heavy-tan for now.
