Superimposed lines - Generally good but for longer lines, your lines seem to start arching toward the end

Ghosted lines - It seems that this exercise is missing. Perhaps you forgot to include it. If you have skipped, it please complete the excercise.

Ghosted planes - You have only completed 1 out of 2 pages for this exercise, please complete it. Other than that, your lines are smooth and confident and now you can focus on improving accuracy.

Ellipses in planes - These look good - smooth and fit within the plane , they just need to tighten up. You have only completed 1 out of 2 pages for this exercise, please complete it.

Table of ellipses - Again, nice smooth ellipses that fit generally don't overlap, just try to keep them with in the boundaries .

Funnels - There is a funnel where there are many gaps between the ellipses and a funnel where the ellipses don't fit within the funnel, the others look better but some ellipses are misaligned with the minor axis. Perhaps you should go over this lesson and exercise again.

Rotated boxes - You did well in rotating the boxes but I recommend drawing them bigger.

Rough perspective - You have only completed 1 out of 2 pages for this exercise, please complete it. Despite this, most of your lines look clean but I can see some places where you redid the line, make sure you ghost until you are confident in the stroke you are making.

Organic perspective - Your lines here don't seem as confident perhaps because you were struggling to construct boxes for imagination. I'd say think about what box you are trying to draw before putting down any marks. Then plot points and ghost your lines until comfortable. Understanding the construction of boxes will come with time and will develop much more in the 250 box challenge. Make sure to read over the lesson and watch the videos on boxes again before you start the challege and during it if you get stuck.
