Hi, Massive_Crocodilian. Good job finishing this lesson.

Lines

Your lines look good. In some cases, there is some noticeable wobbliness on the ghosted lines and plane, but most look fine. In the ghosted planes you didn't place the dots before drawing the inner lines. Be sure to always plot all your lines with dots, as this gives you a goal to draw them to. If you don't place dots how can you know if your lines are accurate? This will help you check your improvement.

Ellipses

Your ellipses are also pretty good overall. In the funnels exercise you could have packed some of them closer together and you seem to have a tendency to draw them slanted. Don't forget to rotate the page, in order to get a better drawing angle, in case you need to. Also, still on the funnels exercise, remember that the ellipses need to be aligned with the minor axis (that center line between the arching ones). The minor axis should cut each ellipse into two equal parts. In some cases you didn't even drew the minor axis.

Boxes

Rough perspective seems OK, as you kept everything aligned with the horizon and, in the end, the perspective ended up being very decent.

Your rotated boxes are very good. You managed to rotate them as asked but, with a better lines work, you could have ended with a more pleasing result.

On the organic perspective exercise although the goal of the exercise was achieved, you could have drawn better compositions. In some cases there is a lot of white space where you could have drawn more boxes. The perspective is acceptable in most of the boxes, but some ended a bit wonky. You'll have time to get better at this during the boxes challenge.

One thing I've noted in your boxes exercises is that you seem to go over the same line more than once in a few cases. Avoid doing this as it defeats one of the purposes of using ink, which is to plan your lines well. Plot your lines with dots, ghost them and draw with confidence. Not all lines will look good, but embrace the result and, when it's not so good, keep it in mind and do better next time. Don't try to cover your mistakes by drawing over them.

You didn't draw the full two pages of the rough perspective. I suggest that in the future lessons you do as asked on the homework sections. I'll still mark this as complete, though.
