Lines:

--Ghosted Lines:

There is some fraying on both ends, so put some emphasis on being more deliberate in the pace of the exercise and lines going forward. It would appear you have the technique for steady confident lines but I see a forced hastiness that adds more inconsistency that could be easily avoided with a deliberate patience.

--Ghosted Planes:

same as above

Ellipses:

One thing that does jump out is the relative consistency of all the ellipses in terms of their degrees. Practicing a great variety will be more helpful to push your advancement. The key things to think about and focus on going forward will be to strive for tighter ellipses. Your consistency is noted throughout all the exercises, which is great. Time is on your side. I would recommend saving either the sheets or at least the pictures for awhile and repeat down the road and then do a comparison to see how you've improved and what are some of the repeated issues that would direct furture focus.

Boxes:

--Plotted Perspective:

Not much to add here. Looks good, now just focus on free hand box construction.

--Rough Perspective:

1st page is decent, the 2nd page is incomplete. Also there are numerous lines that have been reworked that makes the exercise confusing to critique. I'm mixed on recommending a need to repeat it as making more boxes will be a main stay going forward but doing this exercise occasionally for warm-up might be useufl.

--Rotated Boxes:

Unfortunately there is very little rotation throughout the boxes. I would strongly recommend repeating this exercise and go back and watch the video as well as re read the instructions because it will help point out a few techniques on ways to think about space and the boxes that gets lost during your execution. Based on the other exercises, I is obvious you can do this exercise even if it is tough but it will be worth it.

--Organic Perspective:

Same line issues as noted before. Lots of reworked lines, and the appearance of trying to go too quickly. I would use this exercise as a warm-up from time to time but you'll do lots of this in the 250 box challenge so no need to repeat this exercise deliberately.
