After the thinking has been done, after the poses have been laid out, after the acting has been deemd as working – You start polishing. Initially, I saw this as a chore, as somethign that needs to be done AFTER the fun part of blocking is over.
But polishing is much more than that. It is the stage of animation, where the character actually comes to life. This is stage which will aid in suspension of disbelif. It might be a minor ease in, or a minor overshoot but every thing you do will make the character seem more real. The monitor turns into a window and you just happen to be looking at the character doing his thing through it.
So, learn to enjoy polishing. Cause it aint going away.
