Hello! Here's my critique of your work:

Lines

Superimposed Lines

No problems with this, a majority of your lines did not fray the at the start (which was the intended goal), with the exception of just a few. It shows that you took the time to position your pen properly before ghosting/executing it.

Ghosted Lines/Planes

I noticed that many of your lines either were arching or had a wobble with them, more on the latter.

Remember that confidence > accuracy, and that a smooth line is better than a wobbly one. Instead, your accuracy will improve over time, but you should focus on building up confidence to draw your lines first.

Remember that you can rotate your page to draw your lines (to find a comfortable angle to draw with), and to use your shoulder pivot whenever necessary, which may fix the wobbles. Don't forget to plan/ghost your line as many times as you need to in order to, until you believe you can draw that stroke confidently.

As of the arches, you can try to arch consciously to the opposite direction when drawing that said line, while also using your shoulder pivot to draw that said line as well.

Ellipses

Ellipses in Tables

Try to keep the ellipses should be kept within the bounds of the box, as some appear to be flowing out of it. At the same time, try to not to have them overlap each other.

Ellipses in planes

Apart from just a few of your ellipses overflowing outside of the planes, most of your ellipses were kept within the bounds of the plane, while touching all sides of the plane (except for just a very small few). Pretty solid.

Funnels

Your ellipses, except for a few, fit exactly within the funnel without overflowing, which is good. Some of them (meaning, some did and some weren't) were being symmetrical/aligned enough to but cut in half by the minor axis (line in the middle). Still, seems solid.

As a whole, just like lines, don't forget you can ghost your ellipses as many times you need before drawing it. On a positive note, I noticed that your ellipses slowly started "tightening up" more while drawing through your ellipses mentioned at the 2nd and 3rd part in this image, keep it up.

Boxes

Plotted Perspective

No problems with it.

Rough Perspective

Feel free to ghost more to the Vanishing Point until you're more confident that your extended lines meant to go to there hit that point. That aside, I noticed that you repeated some lines. Just remember, no matter how off a line is, a try not to repeat it, keep the line as it if were correct and move on, because you'll risk making it messy.

Rotated Boxes

Your lines were actually quite clean here, but some of your boxes weren't rotating. See this image as a reference. And this image, where I've marked out an error from your work, as an example.

Organic Perspective

Besides some lines being repeated, the linework is rather clean. Though, I noticed that most of your lines were parallel instead of converging to one of three vanishing points. This photo will show what I mean by parallel instead of converging. Don't worry too much though, you'll get to draw more 3 Point Perspective Boxes in the 250 Box Challenge, which will definitely help you understand the concept. This website also includes an interactive demo of a box in 3 Point Perspective, which may help you.
