I can't decide if it's cute or scary: it's got the big cute foxy head, but some scary-ass poisonous claws. And then the heels... i'm definitely scared
You've used a cel-shading on the whole character, i suggest you remove the dithering on the cheek to keep in style (and fighter sprites usually don't use dithering). Try a different outline color on the white parts of her body (head, tail). The arms and shoulders could probably have a bit more definition, perhaps indicate where the shoulder is by changing the shape of her sleeve.
The alternate version is nice too, i like the metal shading. The anatomy is a bit more towards the cartoon and less to a "aggressive" fighter, due to the short legs, but that's part of the style, i guess
. The part where her right leg meets the foot looks broken, try moving that small curve further up the leg (or removing it).
