Richard Yot is an illustrator and animator specialising in quirky characters and worlds. His work is entirely digital but with a large dollop of hand-made charm. He mostly uses brush tools to draw directly on the image, without any filters or effects, just paint. If you wish some more in-depth technical information please check out the Tutorials.
Richard Yot has just released a book: Light for Visual Artists, Understanding & Using Light in Art & Design.
