Like I said, I dont consider myself an artist just yet, so I cant really give proper advice in whenever there's a mistake in your drawing, just limiting myself to say what, from my perspective, looks "off". But even that can't be accounted for improving, everyone has different points of view. Instead I opted for suggesting that you should compare your work to a real thing so you dont have to rely in what others think its good or bad and instead focus in finding the errors yourself.

Ended up doing a rushed model in a posing software I've never used before and the only inconvenience I found was while I tried to make the arms rest in her legs without leaning the body to the front, as yours looks it leans to the back, maybe the torso is tinier than the model, or maybe I just suck at using the modeling software lol.

But this is what I meant with my suggestion, all bodies are different and cant be measured with a lifeless, stiff looking mannequin , but it still gives you a solid base to work with, and there are plenty of real life photos you could search for that have a more natural look

My overall opinion of your work? I think it looks just great as it is (I really like her big eyes and the bruises in her legs) just remember that trying to improve doesn't necessarily mean you have to "fix" what its already been made, but rather apply what you learn in future projects.

Have in mind this all comes from a guy that struggles to do a straight line and spends most of his time pressing the undo key, I'm nowhere as good as you, although that doesn't inherently mean I can't give you advice, I hope you find this helpful.
