Ok, I'm using a plain papers, in place of special smooth drawing papers so that helps me to get a textures in the right places. When i don't need to have that 'paper/skin' texture - I'm using brushes, to blur the pencil.
How you do this I will never, ever know. I wish I could though. I'm ready to hire you as my art teacher lol. Your mastery of shading kills me. I can't even...............dsfghjkl,mnjgfbausjklcfmnasncffas
Amazing job once again. Even Dr. House would be rendered speechless at this.
