A PROFILE PORTRAIT STUDY OF AFRICAN GRANDMA

Good evening to you all, here is a sweet typical example of African Grandma with the facial mark of recognition and beauty of each tribe or city in Nigeria.
A profile portrait study of African Grandma.
I have always been an enthusiastic lover of the profile portrait, But learning how to draw a face in profile does come with its different of possible errors,
So this kept me putting more practice and understanding some calculation over it.
Challenges on profile portrait view
Challenges facing without using Gridding method
Calculation of Eyes, Nose, Lips and Ear .By drawing faces, I use to be sure not to place the ear too close to the eye. It is usually equal to the distance between the chin and the corner of the eye.
Watching all this bring my drawing to perfection looking at nose to eyes how small the visible part of the eye is relative to the size and structure of the nose.
starting profile portrait drawing, the angles between the forehead and the tip of the nose, and the tip of the nose to the chin must go in line in mere looking at the face.
