And now, the most requested tutorial, the Fur tutorial.
Fur is either really complex, or really simple, depending on what you're trying to do with it. I find this technique seems to work with whatever kind of fur I need to paint. (Skipping steps for more simple stuff, adding steps for more complex stuff).
Just remember that it *is* very important to study animal structure. Fur cannot hide poor anatomy skills, so it's very important to brush up on that. You could make really stunning, fabulous fur, but if your anatomy is off, it'll make it look as if your fur is off too. Also remember that fur flows on the body in certain patterns, so study that too!
