A blog I have followed for ages is Rob Richards' wonderful 'Animation Backgrounds'.
Carefully recreating the original backgrounds by compiling screenshots, the full backgrounds are pieced together to create some startling images that just don't shine while watching the films themselves.
One favourite of mine from his site is this wonderful background from the Bumble Boogie' section of 'Melody Time'.
The latest post looks at 'Beauty and the Beast'. I have never really considered 'Beauty and the Beast' as have the most artistic, creative or individual style of all the Disney animated films, but looking at the backgrounds from themselves they are truly insping. Soft golden, reds and browns create the whimsical, provincial feel wonderfully.
Several of the backgrounds tend to share a hint of Mary Blair too I feel. Those familiar with 'The Adventures of Ichabod and Mr. Toad' will see a certain correspondance with the style of the village, which was of course was heavilly inspired by Blair's concept art.
Any way I strongly suggest you take a look. It's site you can get lost in!
