For my box interior drawing, I arranged a cylinder and five small rectangles in a rectangle container, within the interior of the box. I painted the objects with either purple or orange acrylic paint, and painted the interior of the box black, in order to make the objects stand out. I based my drawing on the view of the box as shown in the photograph below, with the exact angle and lighting arranged.
This is the thumbnail sketch I did of my drawing, I drew out the vanishing points and the perspective of the box interior, using the angle-finder.
This is my finished drawing with fully developed values.
