Hello! Good job finishing the lesson. Let's get it critiqued!

Lines

  • Superimposed Lines

Good, fraying only on one side, which is expected and fine. Some wobble - this can be mitigated with focusing on the end point of the stroke and executing confidently.

  • Ghosted Lines

Well done, with some slight wobbling here as well. Again, more confident execution should help this. Once the pen touches the paper, commit to the stroke, there should be no hesitation. It can't hurt to remind yourself to use the shoulder for the strokes as well, just in case.

A few cases of arcing, you can try to counteract this by consciously arcing the line the opposite way slightly, which will become less conscious over time and compensate.

  • Ghosted Planes

Not a lot of issues that weren't in the previous exercise, which makes me believe you took your time with this and didn't rush. Good job! Suggestions from previous exercise apply.

Ellipses

  • Tables of Ellipses

These are drawn through 2-3 times as required, laid out snugly against the borders of the table and each other, which is good.

Some wobbly and uneven ones here and there. Taking more time to ghost thoroughly and being mindful of executing confidently from the shoulder without hesitation should help.

  • Ellipses in Planes

These are done pretty well, drawn through, effort was made to try and make them touch all four sides. Some came out a little deformed as a result, trying to fit into the planes; you shouldn't worry about fitting them too much, just focus on the confident execution of an even, smooth shape first. Same suggestions as the previous exercise.

  • Funnels

Ellipses are drawn through, aligned with the minor axis and kept snugly against each other. The only issue is that some are spilling out beyond the sides of the funnel; do your best to keep ellipses snug inside in the future!

Boxes

  • Plotted Perspective

All done correctly. Some vertical back edges are slanted, which is expected and should be minimized by taking more time to align the ruler.

  • Rough Perspective

Looks good to me. Some lines are slanted, taking more time to ghost lines thoroughly should help avoid this in the future.

  • Rotated Boxes

You did the core setup correctly, drew through the boxes, kept the gaps nice and consistent, and applied rotation well.

However, you seem to have forgotten to draw the four outermost boxes in each corner. I trust you to finish them without requesting a revision, as you seem to have understood the exercise well enough. Just make sure not to rush these.

  • Organic Perspective

You did well to keep the boxes consistent, scale them with depth, and refrain from dramatic foreshortening. I notice a few cases of parallel edges diverging rather than converging, though. I suggest revising this part of the Rough Perspective exercise to avoid this in moving to the 250 boxes challenge.

In conclusion: You did pretty well. I believe you're good to move on to 250 boxes after finishing the missing Rotated Boxes.
