Congratulations on completing the lesson!

Your superimposed lines looks fine, there are no wobbles and just few are arching.

You started well in ghoted lines, you didn't fray on starting points. Lines are consistent as well as confident though should improve connecting the endpoint in time.

The planes tend to connect at the center that's good. Ellipses are wobbly but we can solve this by ghosting first before putting the nib down. In table of ellipses, they are neat in sizing and well adjusted in spacing.

In your funnels, you need to prioritize confident lines than precision. Keep in mind that the minor axis (line in the middle) should cut the ellipses in symmetrical halves.

Plotted perspective is fine

The lines are bit wobbly in your rough perspective though the estimates are good. Examine if your height lines are perpendicular to the horizon and width lines are parallel to the horizon.

Your boxes aren't rotating but this assingment is really a struggle and you got through it so well done.

Organic perspective, the work on gradual sizing of each boxes are good. Your boxes are shallow and have diverging lines, instead of receding in perspective.
