Congratulations on finishing a long and difficult challenge!
Even though sometimes the lines are off, you did a great job drawing just one confident straight line, without second guessing yourself, wobbling, or drawing over them. You have a good variety of different shapes and orientations of box, which shows that you explored the rotations and 3D space.
I can see that you sometimes extended the lines in the wrong direction, but you also seem to have noticed as you did that and self corrected. Sometimes if a box comes out really off, it can be hard to determine which way the converging lines should come off, but a good general rule is to extend them away from the first Y that you drew when creating the box.
Try giving more line weight to the outer edges of the boxes. It's not required for you to repost, but I think you should give it a try (do a couple of pages of your boxes) to see how that changes the looks of the boxes, and also to practice superimposing lines with accuracy to add line weight.
Move on to lesson 2. Try giving critiques to other students.
