Heyo, hope you're having a wonderful day!

Imposed lines: They all look great, however they do tend to arc a bit towards the end of each line. Remember to just go with the flow and not think about making your mark too much, other than that, keep up the good work.

Ghosted lines: They all seem to be very accurate, but confident as well. Nice. I do see that some of them do wobble just a tiny bit, but you'll get the hang of it no need to worry about it too much.

Planes: They look accurate and so smooth, it's really neat, I did see that a few were curved and arched in a bit of a weird way, try to warm up with the imposed lines and then ghosted lines so that making marks won't be as wobbly and arched. Other than that, they look pretty neat.

Table of Ellipsis: They look great! But you do want to keep the loops to about 2-3 loops, but they still look fairly accurate and they all fit well.

Funnels: They all fit snug inside the funnel and feel pretty confident, however the transition for one of them feels off, what I did for mine is that I put the thinnest ellipsis in the center and then put the largest ones on the ends. Idk, if that'll help out or not really. But other than that, they looks pretty good dude, just remember to keep the loops to about 2-3.

Ghosted planes: The planes look good, I do see that you kept some of the ellipsis to about 2-3 loops, nice one. They feel pretty confident too, and they fit well into the planes.

Plotted Perspective: Looks cool, no comment.

Rough perspective: The lines for the boxes wobble a lot here, try to warm up before drawing boxes so that your muscle memory is good to go, and so that you won't wobble as much. The boxes seem accurate too.

Rotated boxes: This looks amazing, the way the boxes almost make a perfect sphere is amazing! Only thing is that it's a bit hard to see because the face of each box that is facing us, have thin lines. Only suggestion is to make some lines a bit thicker so that it'll be easier to see. Other than that, great work!

Organic perspective: The lines on the boxes do wobble a bit, but the perspective does change with how far the boxes are implied to be, which is a good thing. Just remember to work on that confidence with the lines and you'll be good to go.

Hope this helps!
