Hello there! This is my first critique, but I will deliver the feedback to the best of my ablity

Line

You did a very good job for the superimposed lines. Wobbling is relatively uncommon when you do it with (I assume) your preferred direction. It becomes much more notable however, when you try to do it from right to left, but this also corrects itself overtime. There is also no fraying on the starting point, suggesting you did take your time with this exercise, so well done.

For the ghosted lines, there is also no wobbling and quite confidently done, although some of the lines arc a bit. To fix this, try to use your whole arm, as well as trying to pivot a bit to counteract your instinctual to curve. Nevertheless, I'd say you have successfully conquered level 1.

Some of the curves are present in Ghosted plane, albeit is very small quantity so that's a huge improvement. You have also taken your time with the exercise, which is encouraged, so congratulations!

Ellipses

You ghosted you ellipses well, and allowed the ellipses to fit into the tables, which is a great sign that you understood the assignment. Some of them did not touch the border, but that's completely okay. Same for the planes, which also maintain their form despite not touching the corners. Your funnels also maintained their form. Some of the ellipses missed their minor axis point but you made an attempt to correct them with the middle ones, so I'd say very well done.

Boxes

Nothing much to say for the Plotted perspective one. They are great, although you could spend more efforts on defining the edges with hatching as many of them look rushed. This doesn't undermine the actual quality of course, but be more mindful with your choice.

With rough perspective, the attempts are very good, and I think you improved exponentially after a few of them. In the first ones you probably realized that the side lines should not be parallel with each other, and corrected them in the final three. Really great example of how line extension helps out!

Rotated boxes was extremely well done so I don't have much to say

For organic perspective, most of your attempts flow and have convergence, but the 4th one in particular has too many boxes with parallel lines. Keep in mind that convergence is important (but not so much that it becomes dramatic shortening), and prepare this knowledge for future 250 boxes challenge.
