Hi, I'll be reviewing your work. I hope this critique will help you improve.

Superimposed lines are looking good. Fraying on the other end but that's fine. Arcing lines on the longer lines can be worked on by putting in a conscious effort to arc it in the opposite direction.

Ghosted lines are looking good.

Ellipses in planes are looking good. Although some of the ellipses are wobbly and deformed. wobbliness and deformed lines/ellipses are from hesitance to go through with the mark you're about to make, once your pen touches the paper, you should go through with the mark, with full confidence. Even if it misses the intended mark entirely.

Ellipses

Tables of ellipses have ellipses drawn through 3 times, with passes that fall inside of the boundary. Good job

Funnels have ellipses inside the boundary. I see you corrected the funnels with the minor axis' off.

Boxes

You did well on the Plotted perspective exercise.

You did well on the Rough perspective exercise, I can see that you improved on the second page.

Your boxes in the Rotated boxes exercise show you have a great understanding of perspective. the boxes are drawn tightly and confidently. some boxes are off, but otherwise you've done a really good job.

Your pages of Organic perspective are done well. a few diverging lines.

These will go into your warm up pool. Have patience in the 250 boxes challenge.
