Ball with Tail
In my first version, the ball stayed in one place and kept jumping up and down. My tutor said this was a repetitive and meaningless motion, so I changed it. The animation should start from frame 80, where the ball begins to jump forward instead of staying still.
The tutor also mentioned that the starting pose was wrong. The tail should point upward in an S-shape when preparing to jump, and during the squash and stretch movement, the tail should press forward to show anticipation.
Another issue was the tail follow-through. My tail moved too stiffly. I need to make it more natural by adding delay and overlap, so the motion feels more fluid and elastic.
The tutor drew frame-by-frame notes for me on SyncSketch, which helped me understand the correct arc and drag.
Pendulum
In the pendulum animation, I had a similar problem. The tail (or the rope) moved too fast, which made the swing feel unnatural. My tutor suggested adding more drag and delay, especially near the end of the swing, to create a smoother and heavier feeling.
