Hi there.

Congratulations on finishing the first lesson.

So starting from the superimposed lines, the lines are well done, but on the superimposed lines page 2 from the 7th line till the 11th line there seems to be fraying from both sides. If you feel like you want to rush, taking a break or doing the 50% rule should help with it.

On the ghosted lines, they look good, a very slight nitpick would be trying to make some longer ghosted lines since most of them seem to be around half of the side of the short side of the page.

In ghosted planes, there seems to be a slight loss of confidence as there are some lines that seem to wobble, for example the diagonal line right below ghosted planes, but are still very accurate.

The ellipses seem to most often not touch one of the sides, so maybe compensating by overshooting a little bit might help, as the objective was to have the ellipses touch 4 sides at once(has shown in here https://d15v304a6xpq4b.cloudfront.net/lesson_images/a3c1dd5f.jpg). There are also some ellipses that seem to be bent so as not to touch the sides.

On the ellipses in planes, it seems you have a tendency to go for narrower ellipses even in boxes which would have a rounder one, there are also some that seem to lack confidence and are a bit misshapen.

The funnels look very well executed but on 2 of them it seems the ellipses are not centered to the axis line.

The plotted perspective seems to be well executed, another nitpick would be adding a bit of line weight into the boxes to make them more visible.

On the rough perspective your line extensions seem to go over the horizon line, the most visible difference seems to be the less confidence from your previous lines, which are now starting to arch and wobble a lot more. Do remember that ghosting is almost always required.

In the rotated boxes exercise it seems that the boxes that were supposed to serve as visual reference for the range of rotation are not present which most likely resulted in the narrow boxes, and non symmetrical shape (https://d15v304a6xpq4b.cloudfront.net/lesson_images/0fa240d2.jpg). The main points of the exercise like rotating the boxes, consistent gaps and drawing thru boxes are done correctly though.

Both on the last exercise and on this one(organic perspective), there are a lot more wobbly or arching lines in this one. To prevent yourself from doing this consider drawing faster, has it leaves less time for your brain to try and course correct.

Overall a very good job, but the last few seem to either have been rushed or a simple lack of confidence has the exercises mounted, drawabox values confidence in the lines the most so if accuracy needs to suffer for more confident lines, then you should do so. I think you are ready to move on to the boxes.
