Using that template is generally a bad idea. It doesn't have any proper gravity (her feet make her look like she's floating) and it uses the RTP head on a White Ties body. The forward-backward movement is also unrealistic, and the attack pose has no energy.
However I know that's on of the few templates for anim battlers out there, so...
It does need more contrast, definitely. I also agree on adding a highlight to her hair.
