Well lookie here what showed up in the post today! A painting of Dr.Robotnik by Milton Knight that I purchased from him just last week! I bought a frame for it and it's currently sitting proud above my computer. He had three different pieces of art for sale on his website although I'm not sure if the other two are still available. Either way it's my first piece of original artwork by a professional animator (one who I've talked about on here many times before, mainly for his work on the 90's Sonic cartoon) so I'm happy. Oh yeah, and i contributed a little bit to his Robotnik Toy Chest page. :)
Here's a clip of the man sketching out a quick Robotnik for an extra on the American Sonic DVD. Look how expressive his drawing is in such a quick sketch!
