Detailed explanation of animation adjustment feedback


This week, I shot a reference video and made a preliminary action breakdown (blocking) using the character model. After receiving feedback, I summarized the following points for improvement:

Add eye movements to show thinking state:
Before the action starts, you need to add some subtle movements to the character’s eyes to make it look like it is thinking. This not only enriches the character’s emotional expression, but also makes it easier for the audience to understand the character’s inner activities. In addition, the placement of the hands needs to be adjusted to make the character’s posture more clear and natural.

Adjust posture to make the movement more stretched:
By adjusting the character’s posture, make his movements appear smoother and stretched. This can enhance the character’s dynamic expression and make it look more vivid and natural.

Optimize the eye movement when looking up:
When the character looks up, you must ensure that the eyelids do not cover more than 1/2 of the pupil. This keeps the character’s gaze clear and visible and conveys more emotions. In addition, when looking up, keep some mouth shape changes appropriately and show teeth to enhance the realism of the expression.

Reduce action repetition and increase action diversity:
In the preliminary blocking, there are two actions where the characters point their fingers at each other, which seems a bit repetitive and monotonous. Therefore, the first pointing action can be changed to placing the hand on the table to increase the diversity and layering of the action.

Synchronize the movement of the eyelids and eyebrows:
The movement of the eyelids needs to be synchronized with the movement of the eyebrows. When the eyebrows are raised or pressed down, the eyelids should make corresponding pulling movements. This kind of detail processing can make the character’s expression more coherent and natural.

Avoid overlapping movements of both hands and stagger keyframes:
This is a problem I have always had, that is, the movements of the two hands are often too synchronized and overlapping. To improve this, the keyframes of both hands need to be staggered to create a sequence, even if their movement trajectories are the same. This can prevent the character’s movements from looking mechanical and increase the flexibility and naturalness of the movements.
