I know, that this tutorial has been released, by Victor, a few weeks ago, but until now, I had not be able to take a deeper look at it........... and I think it's pure gold!!!
Seriously, you have to take a look at this awesome tutorial. It clarifys some aspects of how to use the classic principles of animation in a short shot of just 10 frames. There you have a clear explanation of how and why to use the squash & stretch (in a subtle way), the arcs , the overlaps on the eyebrows, the anticipation..........as I said, pure gold!!
