3rd scribble drawing of a women with ball point pen

This is my third attempt to draw portrait in scribble style. This one was so much harder and took so much longer, because of her huge hair. Also i made this drawing so much bigger than the others.
You can assume the size by comparing it to the pen beside it.

Drawing the face part was really fun but the hair was so much frustrating. Now i feel like i am getting addicted to drawing like this.
