Redraw of Kotonoha Katsura from School Days
Submitting this redraw (I sketch messy, sorry) of http://eschergirls.tumblr.com/post/33105778421/captain-kawaii-submitted-kotonoha-katsura-from
I researched the character, found out they are supposed to be Yandere, but otherwise quiet.
Given that, I turned the knife, gave it some perspective to get it away from the head and now it looks like she’s about to slice whomever is in front of her in half. Ironically by fixing the picture, the hair has better movement and it looks more like an action is about to happen rather than her posing. So given that, I also changed her expression to fit the action.
Also hinting at the sexy looks sexier to me. (Look her skirt is about to blow up when she twirls and hacks that guy in half.)
Wicked things are about to happen?
I like that you researched the character and used that research to inform your redraw. I think who the character is is a good thing to keep in mind when drawing a character. :)
