I will not reiterate Pencil's feedback, but I will clarify (seeing that what they said is not as clear) their points and give my own thoughts/personal advice:
For the ghosted planes, you should not try to squeeze more planes (i.e. super small ones) into the gaps between bigger ones, as it clutters the page and makes it harder to discern between dots (Your second page looks much less clogged than your first).
For the rough perspectives, your lines wobble more than in the ghosted lines exercise.
For the rotated boxes page, I see you did put in a big attempt to it, but you should try to give all the boxes uniform dimensions and try to plot their relative positions more relatively.
If you're placing down the dots and are wondering how a box might look like, or if you want to see if any pair of dots are correctly placed, put the whole page far away from you (about 50cm or something), then imagine the box. It increases your odds to see if the dots are correctly placed.
Have a nice day.
Next Steps:
You can continue working on long ghosted lines and rough perspective boxes, as well as nailing down the rotated boxes exercise alongside doing other lessons. Don't overwork, though, and remember the 50-50 method.
