Brilliant body design!!
The face is gorgeous and the spacing of her figure is good, but her chest is a bit oddly shaped- the shape of the top half of her boobs are just that bit to straight- the right hip looks a bit to far out in that position. but the overall position you've drawn her in is very good, some people struggle with it so you've done a great job
The colors seem to dark together (the shirt) but i like how you added the red tie around her neck. the bright color stands out.
I thinks it's great how you've done it more close up only showing a little bit of her legs, it makes the art more striking - in a good way-
