Also, for even more art and concept art, you should go to Claire's Keane's blog and the blogs of other Disney artists she links to. You have to do a little combing, but you can find lots of lovely things. I've been meaning to sort through them all and compile a collection.
Here's the link to the pdf and that blog. Also, a french website with tons of Disney conceptuals.
