I finaly upload my own female anatomy sketches 4 yellowspores. Notice that i use egg shape for the body and mainly female body have curve outline, unlike male's body which is much more masculine.
Study the red broken line and the green line. And keep practicing and if u having a hard time to understand my sketches try to search some reference of portraits of female models and try outline for the basic shapes. This will train ure eyes to look for the basic shapes.
