Several months ago, I saw a collection of sketches Hector the Wolf had posted, and one of them showed his character in all his massive, hefty glory preparing to take a swim. It took me a while, but I colored and shaded it, and Hector has graciously given permission for me to post it. I love the way he draws enormous, round bellies and rumps!
The original line art for this image can be found at THIS LINK. The sketch is in the lower right-hand corner. (Note: This link leads off-site, to FA.)
