Hello willdurness

I think that some of your lines are a bit bendy and wobblyish, in particular regarding the first page of superimposed lines and also a bit in the ghosted lines, however with practice you will get better.

the ellipses in planes exercise came out really well.

regarding the table of ellipses: some of your ellipses are bumpy , some not drawn through more than once and some are drawn beyond or between the various sections.

So try to draw through an ellipse at least 2 times and keep them in their bounds.

However others came out good so I think it's only a matter of practice.

As for the boxes part I can't critique much, it seems very well done to me, so good work on that, maybe someone else could tell you more but I think you did good!
