Yes, KOF heavily inspired my pixel artstyle.

I like that you softened the design (less 'sharp' legs). I think it does make the character more human, and thus easier to read quickly. I don't know recent fighting games, but it seems you applied a drawing style that is closer to King of Fighters (at least the KOF games when characters where at this resolution / level of detail)
Good Job!!, Hope to see her face
