This picture is about a 4, maybe 3.5. The main element is a tiny bit fuzzy, but the expression on her face shows that she's talking. She's not looking at the camera and, instead, she's looking at her audience. Her hand is a little blurred, which shows motion. The frame is pretty much filled, except for some blank ceiling space in the top-right corner. And the angle shows her face well, but not straight on.
This picture, however, isn't so great; it would be almost a 2, like 1.8. For starters, the photographer was WAY too far back. The main element doesn't fill the frame, but is talking to her audience and not looking at the camera. But, because she's so far, you can barely see the expression or detail in her face. The distance leaves alot of junk left in the picture, such as the computers, bookshelfs, tables, and another room; all of this doesn't have to be in the picture. And the angle is almost directly from the right, which only shows half of her face and emphasizes on her ear and cheek.
