Some of this may have been stated already, but:

-I thing she looks too chunky and large (not that I have anything against chunky/large individuals), at least judging from your reference. Particularly, she just seems too wide on her upper torso. I'd make that part thinner
then let the skirt part fan out. I think she could be shorter, though maybe it's because Bombergirl just looks so petite in comparison.

-once more, judging from your reference, the skirt seems too low and the boots too high.

-The leg placement is kind of awkward, they seem kind of backwards?
Her left leg should be the one angled forth, the right more sideways.

-I think you're better off emphasizing either the petal emblem on her chest or the jewel, but both at the same time aren't working out.

(Guess Chris' edit covered a lot of these!)

This is totally subjective, but design-wise, it bothers me a bit that her pigtails are of the same color as her face. Kind of makes it seems as if they were made out of her own skin, which is a creepy thought. I would probably differentiate them by making her "skin" light green or something, and keeping her hair just as it is. You might not be willing to do that kind of change, I'd imagine, so just do what you gotta do.
