Ah, understood. I guess this would've made more sense if I had known about this character and the story! As for the wrist, which hand do you mean? Her right or our right? If you mean ours, then yea. The hand coming from behind looks twisted, but that can just be rotated And they might seem too big, I do not know how big the character is, but those forearms look larger than her entire humerus and a little more. Also seem a little too thick maybe?
And as for facial emotions, I always say to over exaggerate and then adjust! This way, you can push it to make it obvious and dull it down if it reads differently, or is too absurd.
