I had to do some searching online to find photos of little duck feet. Most of them were either hidden by the grass or under water. I drew them last so that I could match the proportions correctly. They were detailed enough that they became too dark, so this is one case where I used the flattened kneaded eraser to lift some of the pencil off, leaving all the lines and details but lightening the lines sufficiently.
I wanted to portray fluffy critters for the most part, and I have to say that this downy little guy appealed to me a lot. I loved doing the soft feathers along his back and chest.
