I have no basics in drawing, trying to learn anatomy and figure drawing, and i think i’m getting somewhere with it, but what i cant understand is how to shade !!!
I mean…i know where should be the light, where the shadow is, and everything in between, but how do i draw it with a pencil ? No matter what i do i end up with ugly bunch of strokes instead of a proper shadow. I even watched videos of people sketching things, and still cant repeat that. Is it some kinda secret angle at which to hold a pencil ? Or “masonic” secret way of herding strokes in one place ? 
Can someone help ? I’d really want to see mentions of tutorials, books, videos, whatever, which teach the basics of pencil shading.
