This is an animation lecture by Grangel Studio about character designs.
To see “Corpse Bride,” you can skim and go to 42:23 to see the designs. But if you want to watch the rest of it, the lecture mentioned the films that Grangel Studio was well-known for character designing: Dreamworks films (Shark Tale, Prince of Egypt, Spirit), Balto, The Fearless Four, and Hotel Transylvania.
PS: The language was Spanish, so you can use auto-translate with English subtitles.
