The legs are way too short. Generally, if you cut the body in half, then the legs would take up most (if not, all) of the half. They're approx. half of the body's height.
The shoulders are too narrow. Generally, they are each about the width of the head (so across it would be 3 'heads' long).
The boobs are too high up. The top of the boobs is usually around the armpit, so they are 'under' the armpits.
That's all I know for now, sorry.
