Hi! Here's my critique of your work.

Lines

Superimposed Lines

Pretty solid. Most of your superimposed lines were only fraying at the end, with a few exceptions, where the start was also frayed as well (mainly on the first page). Just keep in mind to make sure you're positioning your pen correctly, before ghosting a line.

Ghosted Lines/Planes

I noticed some of your lines arching in the opposite direction. Make sure you're using your shoulder to draw your shoulder when drawing your lines. Though, if it still persists, you can it try to arch consciously to the opposite direction while drawing that said line. You may read it up here. Don't forget that you can rotate your page to a comfortable angle before ghosting/executing a line.

However, most of your lines seemed to be smooth without much wobbling, that's great!

Ellipses

Tables of Ellipses

Try to have your ellipses kept within the bounds of the table they're in, without overflowing out of them, or overlapping between other ellipses. Just like drawing normal lines, you can rotate your page/ghost your ellipses as many times as you need before executing them with confidence.

Ellipses in Planes

Most of your ellipses touched all four sides within its plane, except for just a small few, where it missed touching a side otherwise.

Funnels

The minor axis (the line in the middle) should be cutting ellipses in 2 symmetrical halves. Some of your ellipses were aligned to that said axis (allowing it to be cut symmetrically), some were not.

Overall, remember to ghost your ellipses whenever necessary, and try not to have them overflow out of the space they're assigned to (applies the Ellipses in Planes and Funnels exercises as well).

Boxes

Plotted Perspective

No problems here.

Rough Perspective

WhiIe it's really minimal, I noticed that you had repeated some of your lines here. No matter how off a line is, try not to repeat it at all, keep the line as it if were correct and move on. You may risk your lines being messy otherwise.

Besides that, your width lines should be parallel to the horizon line, with the height lines perpendicular to horizon line. Reason being, I noticed that some lines were rather than being slanted/angled than they should be. Here's an example of what I mean from your work. You can read from the homework notes which goes into this problem here.

Though, it's understandably hard to get this down because you may need a bit of precision. You can try to make sure that your points line up to each other.

Rotated Boxes

Just a minor issue, I noticed some boxes were missing? Though that aside, your boxes are rotating, good job!

Organic Perspective

I noticed a few lines of your boxes being parallel instead of converging, shown here. Though, most of your boxes were converging otherwise, which is good. You can check this image to show the difference of converging (expected for 3 Point Perspective Boxes) and parallel lines.

Hello there, hope you're having a great day! I'm here to take a look at your work.

Lines

Your lines look pretty good honestly. You managed to always draw your lines with both confidence and accuracy which is really difficult to pull off at this level. One thing I would like to point out is that in the superimposed lines exercise, you didn't experiment with wavy/curved lines that much. Even though they're harder to draw, I would like you to try drawing them occasionally.

Ellipses

Again, just like your lines, your ellipses look really clean. I saw a couple of ellipses that weren't drawn through but I'm sure that wasn't intentional. In the funnels exercise, you have some misaligned ellipses but that's completely normal for now. Again, in the funnels exercise, you have some gaps between the ellipses. Try to ghost through each ellipse until you get a feel of how they sit on the paper. Also, you occasionally failed to keep some of your ellipses within their bounds. Now, this is obviously not desired but I've noticed that even when your ellipses weren't fitting like they were supposed to, you didn't try to correct them. You still prioritized confidence even when you realized you were making a mistake. Great job!

Perspective

Both rough and plotted perspective look great! Some slightly wobbly lines in the rough perspective exercise though.

Rotated Boxes

You forgot to draw the far-end boxes of the exercise but other than that, I can tell that you followed the instructions as closely as you can.

Organic Perspective

Other than some correction lines, organic perspective looks pretty good! Always remember that trying to correct your lines with ink will only shift the viewer's attention to your mistakes.

Overall, you did an amazing job! I hope you weren't grinding these lessons though.

I'll mark this lesson as complete so here are some helpful links for the box challenge: placing the inner corner, different orientations of boxes. That last link is for inspiration only, make sure to draw from your imagination.
