Hi, I'll be handling your work, I hope this critique is of use to you.

for your lines

Superimposed lines well executed, but there's some wobbling. Remember that a confident line will always have priority over a wobbly line.

Ghosted lines are good. I recommend page-wide lines for this exercise, once they go into your warm-ups

Planes look great, everything is plotted and ghosted.

for your ellipses

Tables of ellipses overall are good, but there's a few that are deformed, remember to prioritize confidence and smoothness over accuracy. Your second page looks more confident overall.

Planes in ellipses look pretty good!

Funnels look good, I feel like you couldve filled the page a tad bit more, but otherwise it's all good.

onto boxes

Plotted perspective shows a good understanding of two-point perspective.

Rough perspective looks good, you understand the point of the exercise.

on your rotated boxes page there are a fair bit of boxes that are not rotating, but otherwise I think you did well.

On your organic perspective page, you did pretty well, and you understand the point of the exercise. There are a few diverging lines, and I feel like you could've pushed it a tad bit with the amount of boxes on the page.

For the last 2 exercises it's normal for it to be as hard as it is at this stage, and the 250 boxes challenge comes after this lesson either way.

Overall I think you did pretty well. I did not see any repeating lines and I hope that will transfer into later lessons and exercises.

also I like the color of the pen you're using
