This shows the technique that I use to do my portraits.
In the second fifteen minutes I continued to work with the 2h lead and the mechanical pencil. Notice I stayed on the left side of the sketch. Also, I was mainly interested in getting the direction of the hair. I wasn’t trying to shade in this step.
In the third fifteen minutes I started with a 0.5 mechanical pencil with 2b lead over the same area I had worked on with the 2h lead. I was doing shading in this step. I tried to get the darkness of the hair as best I could with out pressing too hard on the pencil. I also did the highlights in the earring and darkened the shadow inside the ear.
In the fourth fifteen minutes I went back to the 2h lead and did more of the hair on top of her head. Then I darkened it with the 2b lead.
In the fifth fifteen minutes I went back to the 2h lead and shaded more of her face on her right side. I also darkened the eyebrow and around her right eye and it’s pupil. I also worked on her nose.
In the sixth fifteen minutes I worked on the mouth, the teeth and her left eye. I used the hb lead on the mouth, the eye and nose.
In the seventh fifteen minutes I went to the 2b lead and darkened her left eye and the shadows of her mouth.
In the eighth fifteen minutes I went back to the 2h on the hair and then darkened it with the 2b. I also did her left earring and the shadow under her chin with the 2b lead.
In the ninth fifteen minutes I finished the hair, the neck and the back ground.
They are always full of life.
