bxIvan, you are already doing well with the interior and human figures. It's time to move on to a more complex - human face. Your characters have static facial expressions in all situations. But they are not James Bond on a dangerous mission. The human face has about 40 muscles, they show our emotional state sometimes more strongly than words, especially in such an area as the relationship of the sexes. In a big movie, this is called a close-up, when the camera shows someone's face to emphasize what the person is currently experiencing. It's very emotional and impressive.
