When modeling the turtle in Maya, I initially had trouble with the shell and couldn’t find the right way to wire it, but decided to simplify the shell and later do more details in ZBrush.
At first, I thought that this animation would not involve the mouth expression, so I did not do the teeth and tongue parts. It turned out that the upper and lower mouths of my turtle’s design were not aligned, so the teeth should also need to be modeled.
Then I refined the model in ZBrush to make it more vivid.
