This is just a quick reaction shot when Sushi screams at James for not wearing a mask. James is still wobbly from spinning around. And here’s where I make up for the fact that these puppets don’t have posable faces by adjusting his hat to simulate a contraction of his forehead muscles.
Also notice the nice focus blur in the background. That adds a lot of depth to an otherwise flat green screen composition. When doing this between shots that might go medium to close-up, remember to scale your background and change the amount of focus blur. That’ll trick any brain into thinking this was shot in-camera.
