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.
