This is my most recent practice on a Kershaw Leek. I look at others work and see shading in their bulino. Mine looked like polka dots. So I went to smaller dots and more of them, but really struggled to get good contrast. This pic is the result of dozens of tries, trying to get something viewable. How can I get better contrast and smoother shading? I caught this catfish, and he was a lot bigger than he looks here!
