Here you go Miz Abby with lines. Notice the horizontal line from the bottom of her left eye( facing you) and how far down it is under her right eye. I did the angle lines just to show the tilt of the her head. The edge of her mouth is close to the outside edge of her eye. Just little things like this is what I look for. Just thought this might help also. The white lines are the computer printers addition, guess it wanted to get into the act also.
Thanks for coming to my world today and seeing what is going on. Happy sketching
