Inspiration from John Lounsbery
Another thing to notice is the amount of squash and stretch given to the character. Depending upon the style of animation you are doing will depend greatly on how extreme you will want to go with distorting the character. By constraining this (without eliminating it) you will come closer to getting the feeling that there is a solidity to the character or object. In this scene you can just feel his cheeks and without drawing each individual hair you can feel that he has fur above a solid structure.
In this simple movement the animator has also kept solid arcs in his motion. When flipping the individual drawings the head moves in a nice arc up to the highest point. Notice also that he leads the arm with the elbow instead of just dragging it behind. This gives it a deliberate action so you know the character meant to do what he's doing. Closing the eyes as he moves up then opening them at the top of the action gives accent to the action and can help punctuate the dialog.
Although I have a collection of inspirational scenes that more closely match the characters in my film I find that sometimes it's best to study scenes that aren't so close. It can be very easy to fall into the copy trap. In order to keep things fresh I can study scenes like this and refresh my animation rules without getting lost in how the character is drawn. Sure, I can look at the poses and gesture but I find it best to not copy them directly. This freshness is what I strive for in my work. To me the audience should enjoy the film and not directly notice the animation. I would prefer them to be entertained and later notice that it was animated nicely too.
