Yeah there are a few anatomy issues, mostly caused by the fact that her waist (and stomach area/navel) is placed too low. Her whole lower body is too big as well. It would be fine if seen with a straight-on perspective, but when she's angled so we look down on her a little bit, as the upper body suggests, remember to forshorten her figure and make it smaller the further away from us it is.

It's clear that you've focused most on her upper body, the rest looks rather unfinished. But fair enough, the colouring on that upper body looks neat. In particular, the highlights on her hair and shoulder armor are great!
