in addition to what Ryu said, the chick's feet look as though she's standing on uneven ground.
in agreement with what Ryu said:
the knifehand looks real wierd and...bulky? compared to her other hand.
Maybe people have different proportions for their hands, but that little bunch of meat on the outside of my hand beneath my pinky is wider than my actual pinky by just a little bit. Of course it's not very defined either.
