Snappy Cartoon Animation Techniques

Emphasize snappy animation with lively energy, pose-to-pose, strong anticipation, overshoot, squash and stretch, quick switches in facial expressions, and follow-through on hair and sleeves. 
Give the movements a distinctive rhythm with variation in pacing: Hold still poses firmly for a split second, then transition to the next movement with a quick, bouncy snap. Make it comical and well-timed, but keep the actions easy to read. 
Movements follow: "stillness → preparatory action → sudden acceleration → large overshoot → sharp stop → hair and sleeves sway delayed." 
Facial changes are exaggerated and comical. 
Poses are clear in silhouette, with a solid hold of 0.1–0.2 seconds at the end of each action. 
Use cartoonish squash & stretch, motion blur, short afterimages, dramatic smear frames and speed lines sparingly. 
Physics are slightly exaggerated beyond reality, but the character's footing and center of gravity don't break.
