I kinda see where you’re going with this but the lower half of her feels like it’s being twisted in one way and her left arm seems slightly larger than the other.
I’d recommend looking at this post by @SpergPatrol
There uhh is a lot wrong with the anatomy with this art and the designs so far even without color look kind of bad that ethier, not enough is happening(The tall women), or wayyyy too much is going on (the little girl)
The little girl outfit has a pattern, jester shoes, and a ballerina outfit on top of poofy hair and buck teeth.
This is wayyy to much visually speaking and you may want to tone that down a little and make her have a more consistent theme.
The grown woman is little lacking, it so far is just a lady in a short shirt showing her panties and knee socks, unless you're about to make a hentai parody, this is designed that wayyy out of place especially for the cartoon you're basing it off of.
It has nothing else visually speaking other than the head being a clear copy of the design of female demon news reporter's head. Make the hair different more and the design have more than just what you have so far because it kind of just looked like you made a lewd version of the news reporter at the moment.
The little girl you have drawn so far has got a horse face, it doesn't look humanoid, it looks more animalistic you may want to dial back how much you protrude the bottom half of the face forward.
The grown women's legs look like a horses' also, legs do not curve like that and it looks like the calves you drew have tumors in one while the other just is kind of broken.
The little girl's upper thigh is also broken as you can see a clear lump protruding out in two separate places. Thicker legs do not have curves like this.
Your women's torso suffers from missing ribcage syndrome, there are good references online because this is a common mistakes for beginning artists.

If you want to know how to fix it this is a full guide the same user also made on how to make the anaomty actually work properly.

Sorry for all the notes, but I noticed you were asking for help and seeing details like this and working on them will vastly help improve your art in the long run when you know little anatomy changes like that.
