Prince Eric has an impressive castle, but I'm particularly impressed with the kitchen. It looks roomy and well-stocked, and I could gladly spend many afternoons here not cooking Sebastian (the scene where the chef wrecked the kitchen makes me cringe).
The source of all of these backgrounds except the library is Animation Backgrounds by Rob Richards. It's no longer updated, but there's a huge archive of digitally restored scenes from tons of animated movies - not just Disney ones either. Restoring the images seems like an intense process, and I'm grateful for the work Richards has done. It's easy to lose hours browsing the posts.
Can you recommend any sites like Animation Backgrounds?
