Hi, the section is explained very well. However, I struggle with the last assigment. How do I fulfill "they should have different vanishing points but feel as if they have the same horizon line". I wouldn't even know how to do that for boxes. I think I am missing the point how to introduce more than one pair of vanishing points if you have to depict multiple objects (boxes, cylinders etc.) that it still feels like they are in the same "room or place".
