The "I Believe they can Fly Pig Sketch Challenge!

I'm revisiting a fat sketchbook I started in 2009. There's a lot of empty pages as I selected to sketch in thinner books. But now, it's time. I started this book to paste in old sketches of mine that I could improve upon, but it ended up being a smorgasbord of art product ideas, drawing challenges, and well, just things I wanted to sketch–mostly characters from out of my head.

Recently on Facebook I challenged some friends to post an illustration of a pig. Check here for two friends-Bob McMahon and Barbara Sparks did so, enjoy!:
