I thoroughly enjoy drawing wrinkles, but I must say, my favorite part of this portrait was crafting the seamless transition between the coarse short fur and the smooth exposed skin, particularly around the eyes, nose, and jowls. To achieve the soft appearance of the skin, I start by applying a few very light layers of color. Then, I gently use an eraser in circular motions to create a softer, smoother effect, add and subtract, add and subtract until voila, smooth skin.
