I approve of her remake.
I think -all- of her new animations are a significant improvement to her old ones. Her skipping is very elegant, and alludes to her being more than a simple child because it's not a normal skip.
PS. It is a skip, it looks like a skip, it acts like a skip, and if you were on the moon, it would -still- be a skip.
Her age is more appropriate to here lore, and no, she does not look older than 10, and that's being generous. Which brings me to my next point, her visual remake accurately depicts "The Dark Child" MUCH more significantly than her old appearance did. For this reason specifically, approve of the visual remake.
