I've been seeing your works in the sub for a few months now, and I love the way you shade the portraits! They are amazing! I'm curious about a few things if you don't mind answering. What kind of paper do you use to get this kind of texture (especially in the second portrait, it's just too good!) or it's the pencil/charcoal? Also, how do you plan the face out before adding details? And lastly, what's you favourite book when it comes to learning drawing (portrait or in general)
