I used to send along little sketches with my money whenever I bought something furry-related on eBay. It was good practice, and it got me lots of positive feedback. Some of these sketches came out good, some not so good.

Here's Yasha, Fievel's baby sister from the American Tail series. I actually was able to find a plushie of her on eBay, and this is the doodle I did for the seller.
