Richard Clark:

The smear frame at 67 seems unnecessary. Also, I don't get the color change on the older character's face at the end? Lip sync needs improvement. It's tempting to hide a lot of lip sync in a mustache but even with that, you should try to attempt the shapes according to the phonemes. Just having 2 mouth shapes and going back and forth with them is lazy. Also, not much happening with the posing of your characters. They seem to be stuck in one pose and you're just moving them up and down and left to right. Try to shoot reference before beginning to give you some better ideas.

David S. Rodriguez:

This is good, but I think it could be pushed further with the lip sync being more on point with the dialogue. Otherwise, good job!
