A while ago on craigslist, I found a listing for a 'few boxes of animation supplies' for free and jumped on it as fast as I could. Inside the boxes were countless sheets of various sizes of animation paper and way too many blank cels. I thought it would be cool to utilize those cels somehow and decided to try and create my own cel. I realize that I was using the wrong paints (acrylic), so the colors are all streaky and thin. But it was fun to mess around with it anyway.
(I have a newfound respect for the 'Ink and Paint girls' that the Disney documentaries seem to gloss over constantly...)
