What game is this (possibly recolored) sprite of a girl with a sword from?

I'm developing a game and have some concerns about the originality of the artwork that a collaborator has shown me. A friend of mine tells me that this sprite looks familiar to him but he can't quite place it.

Is this a (possibly recolored or otherwise modified) sprite from an existing game?

Update: It is stolen art. The original has been found here thanks to Martin Sojka.


That's pretty obviously Lightning, from Final Fantasy 13. They've made a sprite version, so not completely the same, but not at all original.
