I took a normal A4 sheet. I drew a head of eyes, nose, lips and outlines for face and hair.
I took the three poster colored jars.
I mixed light brown and yellow and made a watery mixture. For lighter tones.
I mixed light brown and red and made a watery mixture. For darker tones.
I painted the face with the above. I had now three distinct zones in face. Blank, lighter tones and darker tones.
I allowed the painted face to dry under fan. About 10 minutes.
Then I used lighter reddish brown, darker reddish brown, lighter brown and darker brown Mont Marte skin colored pencils. I shaded suitably.
Then using black Mont Marte skin colored pencil I shaded hair.
Then using red Mont Marte skin colored pencil I painted lips.
That's all. Thanks.
