Here's an update on my portrait of Buster. I completed his right eye and worked on his chin a bit. Tonight I used a 0.5mm Pentel Mechanical Pencil with a 2B lead. I blended using a medium tortillion with light pressure. I used a Tuff Stuff eraser pen which I cut at an angle so I get a sharp edge which I use to "draw" the highlighted hair. I then go over the entire drawing using a 2 inch hake brush. The bristles of the hake brush is very soft so I'm not worried about smudges but I feel that pulls everything together nicely and gives a nice polished look to the piece; though it may not do anything really but I do love to use it :-)
