I remember a variety of visual BG development for The Black Cauldron. This beautiful Bg is by Ron Dias. It represent a throwback to old classic Disney, very romantic, and also well executed.
Gosh, you wonder what this movie could have been.
To me the film's problems lie within the insufficient story telling as well as often lackluster character animation
Fortunately better movies would follow, and eventually we were on a roll with animated films that resonated with modern audiences.
