Progress:
I originally plan to practice walk to sit and stand to walk actions, which are basic body mechanics movements.
But Ting thought it was too much workload, so I cut it to stand and walk only.
I studied the human shape walk cycle online and made my own version. I learnt deeper about how the human body can be performed as a bouncing ball.
Then, based on Ting’s advice, I made the character more cartoonish by adding more reasonable overlapping for different parts of the body. I understand that from root to head is a pendulum or squirrel tail, the leg and arm are also tails that the upper part will drag the lower part. And I come up with the idea by using the blue pencil tool in Maya to draw the overlapping guideline, and also the line of action that I want for root control. Here is what I got:
