I love the sprite, though the selective outlining might look better against an actual background. Got one you can toss it against so I can maybe see it in mockup?
I'm not a big fan of "bouncing" idle animations, and I suggest trying to push coming up with new ones. The pose is great, though (man she is thin!).
Arms seem a bit bouncy and some pixels jiggle a bit too much out of place, its a good sprite though.
Use your Pixel Pin powers.
