Richard Williams is a fascinating figure in animation history. He was a man with great ambitions for animation, but unfortunately was undone by his lack of financial stability.
During the 1970s, he brought some of the best of the Golden Age animators such as Art Babbitt, Ken Harris, and Grim Natwick to England to teach his animators how it all was done. That helped improve the quality of the animated commercials Richard Williams provided by lightyears. Here are some samples of the work his studio did.
The only issue I have with these is Williams' insistence of animating on ones. Now, in some cases, it could be beneficial such as if you were animating in a more realistic fashion. However, it can be a bad habit if you are animating more cartoony characters such as Goofy and Donald Duck in the Fanta commercials. Doing it all on ones gives the feeling as if they're somewhat floating and not entirely grounded.
I hope to reach that level of expertise that Richard Williams and his animators reached in these commercials.
