Hello Elvinzoriapa, congratulations on completing Lesson 1. Here are my thoughts,

superimposed lines: slight arc can be perceived, this willl diminish with practice or you can choose to arc consciously in the opposite direction

ghosted lines: a wobble can be seen in some lines, just remember to ghost your lines and execute with confidence. Don't hesitate and prioritize stroke smoothness over accuracy.

table of ellipses: remember that you should only be going over your ellipses 2-3 times and to keep each pass tight. Some of your ellipses ended up looking messy. Also don't worry about being able to draw ellipses in a clockwise manner, just focus on getting the points highlighted in the material correctly. I'd also suggest you start practicing with ellipses that are much smaller, as this will come in handy in Lesson 3.

funnels: at times the ellipses wont be aligned to the minor axis

rough perspective: remember that width lines should be parallel to the horizon and height lines perpendicular to the horizon. It's also worth mentioning that you should not be going over lines in a attempt to correct them. Even if you missed bady, just move on as if it had been correct.

rotated boxes: at times your boxes aren't actually rotating . See the center left row.

organic perspective: as you noted yourself, some of your boxes have foreshortening that is too dramatic. This was reduce on the second page though.

Conclusion: Overall a solid submission. I do suggest that you practice the funnels exercise one more time though, keeping in mind the points highlighted. Besides that good luck on the 250 Box Challenge.

Best of luck moving forward
