Here's an update on my portrait of Buster. I'm using a Pentel 0.5mm Mechanical Pencil with a 2B lead for the darks. For lighter tone, I'm using a 4H lead. I'm blending using a medium tortillion and soft tissue paper. I pick out lighter strands of hair/fur using a Tuff Stuff eraser which I cut at an angle to get a nice sharp edge. For highlights, I use a kneaded eraser which I pinch together to get a nice sharp edge. I'm still making adjustments to the tone but I'm going to moving on as I try to continue to bring Buster to life on paper.
