Rough anatomy

I have been sketching and drawing for a while after my first step it is important to know what you want to improve on and in my case I should say all of it so for now I have started to focus on the anatomy such as shapes, proportions and getting those right angles and stuff and trying to settle on her face mostly the eyes and nose... I should learn how to draw different kind of noses and mouths. Its all rough and stuff but I am a bit more confident on the lines that I make and using less CTRL Z and drawing more in lesser time. Take note that I didn't do all this in just a day or a week o constantly draw as soon I have my free time.
