Step-by-step: Different expression for different characters
I paint the bored-looking character and I focus on her posture, which will communicate her state of mind. The character is holding her head with one hand. Her eyes must indicate disinterest, so I draw them halfclosed and tight. A mouth with drooping corners is essential to show that whatever she’s watching is not floating her boat.
For the couple, I paint him sitting with his legs wide apart and calm facial expression. I paint his eyes open and mouth relaxed into a smile. But she’s frightened and so I paint her huddled with her knees toward her chest and an arm holding on to his top. Her gaze must indicate anxiety, so I depict her hiding her head between her shoulders.
Now I paint two characters who are interested in the film. The man is concentrating on the plot so I paint a neutral expression on his face but draw his torso bent toward the screen, as if he wants to see things more clearly. The woman is amused by the film so I paint her with a big smile, round out the cheeks and widen her eyes.
