Hey RANDOMY220,

Superimposed Lines

Not much to say about these. No fraying on both ends, no particular strong wobbling or arcing. Well done!

Ghosted Lines

I really like your confidence here! You made sure that you put confidence over accuracy. But you really don't have to mark your starting/ending points with A/B. ;)

Ghosted Planes

Sometimes, but rarely, I see a bit of wobbling towards the end of your lines. So make sure, as mentioned above, that you value confidence over precision. So better a confident line which is a bit too short or too long, than a wobbly one. But all in all great job.

Tables of Ellipses

Here sometimes your Ellipses changed their degree within one section. Try to avoid that. Also, especially on the second page are a lot of Ellipses or even almost whole sections a bit off in their positioning -> they neither touch the top or bottom bounds of the frame. So watch out for that. But the confidence is mostly there, which is the most important thing at this stage.

Ellipses in Planes

Here as well, nice confidence. I also like that you don’t stretch out your ellipses needlessly to hit the bounds.

Funnels

Here you tried to keep the Ellipses aligned them to their minor axis. Some of them fit pretty good, but a few are off in their rotation. Remember that the minor axis should divide your ellipses into two perfect halves perpendicularly.

Plotted Perspective

No problems here, although in the first box you hatched in the bottom plane of your boxes, which we normally wouldn't see. But you did it right in the second and third section.

Rough Perspective

Here you, as a lot of people do, loose a bit of that confidence and your lines began to wobble a bit. So make sure that you always plan out and ghost your lines sufficiently.

Rotated Boxes

Before anything, I wanted to congratulate you on its completion. It's not something you're really supposed to be ready for. I like that you kept the gaps between the boxes consistent and your lines fairly confident. The main problem I see is that your boxes aren't rotating enough. And that the outer corners I marked here are pushed out too far. Take a look at Uncomfortable's example again and you'll see what I mean.

Organic perspective

Here are a few perspective issues, but you'll work on that in the 250 Box Challenge enough. I really like, that you didn't try to correct or fix any lines that were off/wrong! That is something you should keep avoiding! ;)
