Tbh I don't think this is any better than the set.
But I'll get on the details to be a bit more specific:
-Red pins having so much black pins in the original set, why change them to red ones? Like with all mocs they stand out, but in this revamp they stick out even more. I imagine you used those for other stuff but still, should have kept the black.
-The weapon: My main issue with this is how cluttered it looks, and the yellow looks out of place here, if anything that weapon should go with her previous version.
-The limbs: Not too bad, but they are a bit lanky, what I do not like is the shoulderpad you gave her, it looks very odd.
-Other details: the vent piece she had in her back is gone, and the one that is there now doesn't flow very well. I personally do not like the leg design in which the crystal armor is on the lower legs.
Overall I'd say this is a mehish revamp, it has as many flaws as the original. 5/10
