The new cloth colour(the old hair colour) doesn't mesh well with the 5th skin tone used on the clothing and the headband.
Using outline colour instead(as above) could help with this, though this makes things alot darker, so you'd want to edit in some 5th skin tone as anti aliasing, since the majority of it will be removed to make the clothing actually look ok.
The hair makes no sense with how the headband is, and the headband gets randomly cut off, see how the tie up on it makes sense on Echidna? how it's outside of her hair? if you wanted the headband to tie up under the majority of her hair with a knot on the side, this isn't the way to do it, maybe get some pictures of headbands and hair ties before you try something like this, so that when you do it it actually makes sense.
The necklace is symmetrical and disregards the angle of her body, the cord/chain is extremely dark and stands out like a sore thumb against the skin.
Above ^, is how I've shaded a necklace, you're welcome to reference that when fixing this one.
You've also changed her eyes from light to dark, when doing this you should always revise the shading as light hair/eyes/clothing/skin/etc are shaded differently from dark ones.
Your third skin tone looks a bit off, it seems a bit darker and a bit less saturated then it should.
