Um, 1st I have to say Im a he, not she -.-; quote my title next to the avatar x.x
The eyes first of all should be more circular, it looks very cubic...o.0 The "ribbons" should be clearer and thicher, also try having them not attaching to each other. Dittering isnt a good way to shade this sprite, due to that it is small and its smooth since it is water-ish. The rock on the body is good, and the shading is fair, just fix what I said =)
