Hi Toadonatoadstool, I'm going to do a little analysis of your lesson.

Superimposed lines: your lines are arched and have fraying on both sides, so you should pay more attention to the beginning of the line and try to curve it in the opposite direction.

Ghosted lines: your lines have a small curvature, but it is smaller than before.

Ghosted planes: not bad!

Table of ellipse, Ellipses in planes and Funnels: You did well, only some ellipses were a little deformed.

Plotted perspective: OK. These errors are normal.

Rough perspective: you forgot to extend the lines of one of the boxes.

Rotated boxes: This is great.

Organic perspective: you used line weight in only one of the frames and could have used it in the others. You will improve your boxes over time.

Overall it did well. Don't forget to use these exercises as a warm-up before drawing and reviewing the points I criticized.

Your lesson is complete.
