Starting with the rotated boxes, it still appears to be unfinished. As shown here, you drew one face for one of the corner boxes, and left the others out. You also have a tendency to overcomplicate the basic squares we use in this step to define the extremities of each axis. Do not deviate from the instructions.

To your point about the framing/division of the page for the rough/organic perspective boxes, I get that the steps can be tedious, but you are not in a position to choose which instructions in this course to follow, and which to ignore. All you can do is your best to consciously follow those instructions to the letter. You're not wrong that drawing bigger certainly helps, but in the design of this exercise, I've found it to be more beneficial to have students tackle this exercise in this way despite that. Again - it comes down to following those instructions and not deviating from them, because you don't know where I've made conscious choices towards certain ends.

You are indeed applying the line extensions for the rough perspective boxes correctly now, so they're certainly looking better. I can see a slight tendency to have some lines fall short, but as a whole the execution of your marks is notably more confident here than the ghosted planes, which does still suggest a step in the right direction. Undershooting usually comes from a fear of overshooting, choosing one issue over the other. For now, I'd lean more towards overshooting, and gradually reel it back with continued practice.

So, from where I'm sitting, I'll call the rough perspective boxes complete, but since you haven't yet completed the rotated boxes in their entirety, I'm going to ask for another one of those. I can see that your execution of the exercise is actually pretty good towards the center (you're maintaining even spacing and using neighbouring edges as hints for new edges quite well), but this tends to fall apart more as you reach those corners. It's not uncommon for students to lose motivation when things start to fall apart, and in turn, to end up stopping prematurely as a result of that loss of motivation.

Ultimately you are not a creature who acts purely on motivation, however. You are human, and can choose to complete the task even if everything is falling apart around you. Make those conscious choices, and see it through, following those instructions as closely as you can and allowing the results to come out as they wish.
