ive drawn a billion asaro heads dude, it does not tell you how to render. i need to learn how lihgt and shadow and color works. and actually i think your approach is ass backwards. you shouldn't learn to render on a complex shape like a head. i would want to start on cylinders and spheres first so i understand the principles and then can apply them to more complex shapes like heads. thats what im looking for.

But i don't understand pic related and just copying it doesn't help. I need a teacher to explain why some parts are lighter or darker so i can logically figure out what values to use on each plane. but i can't find tutorials or books like that.
