Portrait of the artist as a young pig.
I 'saw' this face in the nap of a pillow... it appeared as a faint shadow in the nap of the fabric. And since I liked it so much I sketched it on the spot. Actually it was only the face that I 'saw'. I made up the rest.
Later I had an idea for a sketchy line style in photoshop. I wondered if it would work. And it did work... almost the same as I imagined. That's one fun thing about digital complexities. Sometimes if you can imagine it, you can make it real.
