Nice job finishing the challenge!

It looks like you put an emphasis on keeping your lines parallel on the page instead of considering your boxes as objects in 3D space. This graphic from the discord explains a bit what I mean. By keeping all your lines parallel on the page you loose a lot of information about how the box sits in space. If you look back at your homework for the plotted perspective and organic perspective exercises, you can see that lines that a parallel in space end up converging on the page.
