As a character designer, you will need to learn the art of squash and stretch. Think of a water balloon being gently pushed in a downward motion on the table. Here, the weight is evenly distributed outward, then imagine it being lifted up again a little bit quicker, this is where the balloon “stretches”. It will attempt to regain it’s natural shape but not before it “squashes” itself into itself! When you get a chance search through the piles of ideas in the reference section.
