In the past, I've made a few pages of "How to Draw A Furre" which was zipped into a file and available to download, but that was drawn up back in 1998, and it's a bit dated.  I don't draw like that anymore...or at least, not in that way when it comes to constructing the character with the pencil. 

Recently, I've made some newly updated How to Draw a Furry pages, which includes a very updated basic body construction, construction of the head, as well as the digigrade leg, and a feathered wing, and a bat/dragon wing.  If you would like to see the new How To pages, you can click on the links below, which will open the How-to picture in a new window. 

Please keep in mind that these tutorials are not a final say in how to draw something.  They show people how I draw it, and I'm by far not the best artist out there.  To fully understand how to draw something, I also recommend getting some art anatomy books, or even take an art course on anatomy.
