first off, the coloring is lovely, excellent work on that.
it's a great improvement from your last one, that's for sure.
the background compliments them very nicely, so kudos on that.
one of the first things i noticed is Fi's face. it looks really long, and there is no actual structure to it, it looks like her face was pulled down, and her eyes aren't aligned. her nose is very long as well.
what also stuck out was her tiny waist, it looks really small in comparison to her hips. also, her shoulders are too broad, what i find helps is the "hip to shoulder ratio", meaning the shoulders equal the hips, if that makes any sense.
but i love the coloring on her dress, i just love it, especially the folds.
what i see you struggle with in this piece is the face anatomy, because zelda's face also looks very long, and her nose just seems incredibly big.
fi's hair also seems strange, uneven i guess would be the right way to explain it.
zelda's hand is also very tiny, along with her wrist. the fingers are really long.
i like her hair though, no complaints there, and that subtle blue highlight you used is great!
there should be more highlights on zelda's torso, however
This is really a wonderful remake. Your style is keeps getting better and more beautiful, the anatomy is much better and the same goes for the objects and accessories. I love all your styles, coloration. The simple colorful background is fantastic. Another great work very well done.
