Here, I red-lined your drawing.

It was a bit hard to red-line since, well, it's a chibi and also it's drawn in a stylistic manner where everything is supposed to be distorted, or miniature. I also didn't know if you wanted just for the body/position or face. Anime is a bit hard for me to critique.
So I made a character sheet, and I know what I drew doesn't line up, but I wanted to show you how the anatomy is built in an easy way.
The joint is like a ball, (like a ball-joint doll) and when an arm, or a leg is coming foward, it overlaps the joint. In your drawing, it was a bit hard to see that, making the elbows a bit wonky looking. I drew to show you how the foot would look hanging like on the girl.
The hands are difficult because, since they're crossed, it shows a lot of fingers. I'd suggest, just drawing a gesture of it, so it shows the gist of the movement of the hands, but not drawing all 10 fingers.
I hope this helps. I can always help red line anything else.
