examples of motion frames

motion frames are what happens in between actions , the fast movement that takes they eye from A to B, they don't keep with the structure of the character and are often put in to fast to really see, but they are there and are necessary for the eye to make sense of the characters motions, they can also be at the end of the frame to extenuate a look or gesture, such as eyes bulging, star effects or sudden changes in expression

see Lolas arm, it doesn't physically look like that when moving but the fast action would make it look blurred, this is how it is done in animation to make the fast motion look convincing
